Darrisaw (knee) was seen leaving the Vikings' locker room on crutches following Thursday's 30-20 loss to the Rams, Andrew Krammer of the Minneapolis Star Tribune reports.
Darrisaw suffered a knee injury just before halftime and immediately went to the locker room and did not return to the game. Coach Kevin O'Connell did not have further information Thursday night, but he did say he anticipated an update Friday.
