The Vikings offensive line sustained two injuries during Sunday's 20-17 loss to the Buccaneers.
Left tackle Christian Darrisaw limped through the postgame locker room after playing through an ankle injury suffered in the first half.
Center Garrett Bradbury could not play through a lower back injury he sustained during the Vikings' second drive. Bradbury limped off the field after a 30-yard completion to receiver Justin Jefferson in the first quarter.
Coach Kevin O'Connell classified both blockers as day-to-day. The Vikings have only four days to prepare for a Thursday night game in Philadelphia against the reigning NFC champions.
"Hopefully turn the ankle around and be ready to go," said Darrisaw, who added the injury is not as severe as the high ankle sprain he suffered at Virginia Tech.
Bradbury missed five games last season due to a lower back injury. He played just seven snaps on Sunday before the same area bothered him.
"He had some soreness in there," O'Connell said. "Whatever we decide to go with [Thursday], we'll put together the plan that works while hopefully getting Garrett back as soon as we can."
Center Austin Schlottmann, who started four games last year, played the rest of the game. He would start if Bradbury remains sidelined. Tackle Oli Udoh is next in line, should Darrisaw miss time.
