Tiernan suffered a left ankle injury during Saturday's preseason win against the Giants, Ben Goessling of The Minnesota Star Tribune reports.
Tiernan struggled a bit in his first NFL game action after being drafted in the third round of April's NFL Draft. The Northwestern product also picked up an ankle injury, so it wasn't the preseason debut he had envisioned. Coach Kevin O'Connell didn't elaborate on the extent of Tiernan's injury, and it remains to be seen if he'll be able to play in Minnesota's next preseason contest, which is slated for next Saturday against the Ravens.

Vikings' Caleb Tiernan: Drafted by Vikings
Rotowire
The Vikings selected Tiernan in the third round of the 2026 NFL Draft, 97th overall.
Tiernan (6-foot-8, 323 pounds) boasts a dominating frame and notable experience, having started the last three-and-a-half seasons at Northwestern. The 32-and-2/8-inch arm length Tiernan logged at the 2026 NFL Combine somewhat undercuts excitement about his size, though he made up for that by showcasing significant explosiveness via a 35.5-inch vertical. Tiernan will kick off his career in a depth role behind LT Christian Darrisaw, who struggled to play through a knee injury in 2025 but should be back to full form for the 2026 campaign.
