Rutgers graduate senior quarterback McLane Carter suffered an apparent concussion during Saturday’s 30-0 loss at No. 20 Iowa, according to a Instagram post by an acquaintance reviewed by NJ Advance Media on Sunday night. The post shows a photo of Carter and says he has a concussion.

Carter did not play in the second half of the Scarlet Knights’ loss at Kinnick Stadium after suffering an injury. Head coach Chris Ash declined to provide details on the injury after the game.

Rutgers (1-1) is idle this coming weekend and has 13 days before it hosts Boston College (2-0) at SHI Stadium in Piscataway. Carter’s status for that game is unclear at this time.

Carter was injured late in the first half of the loss to the Hawkeyes after a rough outing. The southpaw from Texas went 5-of-15 passing for 21 yards and an interception as Rutgers struggled to find the offensive success it had behind Carter in a season-opening win over UMass.

Backup Artur Sitkowski, who lost the starting job to Carter in a training camp competition, came on and played most of the second half. If Carter cannot play against Boston College, Sitkowski is expected to be the starter with Johnny Langan serving as the backup.
