At first glance, the Vikings’ first unofficial depth chart was not especially flattering to Walter Rouse.
Minnesota drafted Rouse in the sixth round of the 2024 draft as a developmental tackle. Two years later, the team listed him as its second-team right guard.
That is not where Rouse expected to be when he arrived from Oklahoma. It is also a clue to the position he now finds himself in.
The Vikings have spent much of the past year searching for more certainty at tackle. Ryan Van Demark arrived in free agency to become the primary swing tackle. Then Minnesota used the 97th overall pick in April on Northwestern’s Caleb Tiernan, a 6-foot-8 rookie whose size and pass-protection profile made him an intriguing long-term investment.
For Rouse, the message was clear. His original route to the roster had narrowed.
Then Tiernan’s first preseason appearance changed the conversation, at least temporarily.
The rookie committed two penalties against the Giants, including two on the same second-quarter drive that helped derail J.J. McCarthy’s possession. He also suffered an ankle injury and exited the game before getting a chance to settle in.
Kevin O’Connell said this week that Tiernan is considered week to week. The coach expressed hope that the rookie could either return for the next preseason game or begin his practice progression the following week, and he does not expect a problem with Tiernan’s regular-season availability.
That is an important distinction. Tiernan is not suddenly in danger of missing the season, and his third-round status makes him a strong favorite to make the initial roster.
But the injury has cost him the exact work he needs most.
Tiernan entered the NFL with a developmental role. He was not drafted to unseat standout tackles Christian Darrisaw or Brian O’Neill. Instead, he was drafted to give Minnesota a young tackle it could develop behind them, then trust when injuries inevitably test the offensive line.
The Giants game showed both sides of that reality. Tiernan has the physical tools the Vikings liked. He also looked like a rookie, with penalties and technique issues that require preseason reps, joint practices and time against opponents who do not know the offense as well as Minnesota’s own defense.
Instead of getting those reps against Baltimore this week, he is rehabbing.
And that is where Rouse comes back into focus.
The tackle plan moved past Rouse
Rouse has not been completely absent from Minnesota’s plans since arriving in 2024. He appeared in eight games over his first two seasons, including seven in 2025, when the Vikings’ offensive line was constantly altered by injuries. The blocker logged 88 offensive snaps last year and received a crash course in the difficult life of an NFL reserve tackle.
Minnesota used 26 different offensive-line combinations in 2025. Its intended starting five, Darrisaw, Donovan Jackson, Ryan Kelly, Will Fries and O’Neill, played only 83 snaps together. The Vikings needed every available lineman just to get through the season.
Rouse saw action at both tackle spots, but he was never established as the first answer.
When injuries struck, the Vikings often leaned first on veteran Justin Skule. In the Chargers game, Skule moved from right tackle to left tackle after Darrisaw left, while Rouse entered on the right side. In other games, Minnesota moved Blake Brandel around the line rather than treating Rouse as an automatic plug-in starter.
Rouse had difficult moments, as nearly every reserve lineman did in that season. Those plays do not define Rouse’s career. They do help explain the Vikings’ offseason decisions.
Van Demark has NFL starting experience and was signed to fill the swing-tackle role Skule had occupied. Tiernan was selected in the third round, much earlier than Rouse had been two years before. The Vikings were not willing to enter another season hoping that Rouse could develop into their only meaningful answer outside.
That does not mean they have stopped believing he can play.
It means Rouse must become valuable in a different way.
The move inside changes the calculation
The first unofficial depth chart gave Rouse that route. He is listed as the second-team right guard behind Fries.
That is more than a cosmetic position change.
Brandel is no longer the Swiss Army knife of the offensive line. He is the starting center after Kelly’s retirement. The Vikings like Brandel’s intelligence, communication and physicality, but he cannot simultaneously serve as their emergency guard and tackle.
That leaves Minnesota with a young, largely unproven group of interior reserves.
Michael Jurgens is the primary backup center. Joe Huber, a 2025 undrafted player, is listed behind Jackson at left guard. Seventh-round rookie Gavin Gerhardt is another developmental center. There are players with traits and potential, but not many with extensive NFL evidence that they can step into a meaningful role if one of the starters goes down.
Rouse has something those players do not: tackle experience.
At 6-foot-6 and 330 pounds, he has the size to work inside. The Vikings also saw that possibility before they drafted him. The team’s draft coverage noted that Rouse could eventually play guard, even though tackle was the more obvious starting point for his career.
Now Minnesota has a reason to find out.
The difference between a ninth offensive lineman and a player who fails to make the 53-man roster often comes down to flexibility. A backup who can only play one position has to be significantly better than the alternatives. A backup who can line up at either guard spot, then move outside in an emergency, can solve multiple roster problems at once.
That is the version of Rouse the Vikings need.
The guard experiment does not require him to become a full-time interior starter, but it requires him to show that he can make the calls, handle quicker interior rushers and play with enough strength and technique in confined space to survive if needed.
At the same time, he cannot lose his tackle value. Van Demark is the first reserve outside. Tiernan is the future-oriented prospect. But injuries happen, as Minnesota learned repeatedly last season. A player who can take a handful of guard reps during the week, then step in at tackle if the game goes sideways, has a legitimate role.
Why Tiernan’s injury matters anyway
Tiernan’s injury does not create a clean one-for-one replacement scenario. The Vikings are not deciding between their third-round rookie and their sixth-round veteran.
They are deciding how many offensive linemen they can carry, how much position flexibility they need and whether Rouse offers more game-day usefulness than a younger interior player who can only play one spot.
Tiernan’s setback matters because it delays the answers.
If the rookie had dominated the preseason, stacked two strong days against Baltimore and clearly shown he was ready to be the fourth tackle, the Vikings could have treated Rouse’s guard move as little more than a last chance to find a role. Instead, Tiernan has work left to do and fewer August opportunities to do it.
That does not erase the rookie’s upside, but it opens a window for Rouse.
He has already been through two NFL seasons, endured the chaos of Minnesota’s 2025 injury problems and seen meaningful snaps at tackle. He now has a chance to add guard competence to that résumé at a moment when the Vikings’ interior depth is far less settled than its starting line suggests.
There is a version of the final roster in which Minnesota keeps Darrisaw, O’Neill, Van Demark, Tiernan and Rouse as tackle-capable players, then uses Rouse as a guard-tackle hybrid behind the starting five.
That roster construction becomes easier to justify if Tiernan needs additional development time. It becomes even more valuable if Brandel’s move to center leaves the Vikings needing another player who can cover multiple positions.
Rouse does not need Tiernan to fail. In fact, Minnesota would be better off if the rookie gets healthy quickly and develops into the tackle it drafted him to become.
Rouse simply needs to show that the Vikings cannot comfortably make their final roster without him.
A year ago, he was trying to prove he belonged at tackle. This summer, his best case may be proving he belongs everywhere.
