Issac went for X-rays at halftime, but the belief is the running back did not suffer a fracture, Brian Hedger reported for the Chicago Sun-Times. Nonetheless, Issac may require an MRI next week to check for structural damage to the shoulder.
Issac left the game with 66 yards on six carries, including one for a 46-yard touchdown. He had another 32-yard touchdown called back due to a penalty.
A five-star recruit, Issac is ranked by Rivals.com as the third-best running back and 19th-best player overall in the 2013 class. He rushed for 2,114 yards and 45 touchdowns on just 178 carries his junior season.
