The redshirt junior was running a zone-read play to the left during practice when he was injured. He cut up field and his left foot hit his back right calf, causing Rowe to land awkwardly on his left leg.
The loss comes as a blow to Maryland’s quarterback depth. Rowe had after played the full second half against both Indiana and Ohio State — and there were questions about whether he would replace C.J. Brown as the starter at one point. Rowe is a front-runner to take over as the starter next season after Brown graduates.
Rowe has completed 34 of 54 passes for 489 yards this season, with five touchdowns and four interceptions.
The circumstances surrounding the injury are similar to when Rowe was hurt in 2012, when he suffered the torn ACL scrambling in a loss against Boston College. His recovery took about six months.
Junior Perry Hills will back up Brown on Saturday against Iowa, while redshirt freshman Shane Cockerille could see time in certain packages should Brown go down. Cockerille, who has been playing on punt coverage the last two games, will be pulled off special teams Saturday in the wake of Rowe’s injury.
