Michael Penix is done for the day, the Indiana quarterback appearing to have rolled his ankle in what is increasingly looking like a win for Indiana.

Penix suffered the injury midway through the third quarter when running the ball and heading out of bounds. As the Indiana quarterback crossed the boundary at the end of the 21-yard run, he slowed up and them tumbled, seemingly injuring his right foot. It looks like some contact made at the end of the run might have thrown Penix off stride, causing him to land awkwardly on his right foot.

It is unclear precisely Penix’s injury let alone the extent of what happened.

Two plays later, Indiana running back Stevie Scott ran one-yard for a 17-3 lead for Indiana.

It is a tough blow for Indiana as Penix has been a bright spot all season for the Hoosiers who are 4-1 and No. 12 in the nation. While Indiana will likely be able to see-out Maryland without their star quarterback, the long-term injury outlook for Penix is problematic.

Next week, Indiana plays Wisconsin, who come into the game 2-1 and No. 18 in this week’s AP Top 25 Poll.

Penix struggled against Maryland in what was easily his worst performance of the season. Touted several weeks ago as a Heisman candidate, he was just 6-of-19 for 84 yards with 29 rushing yards at the time of the injury.
