Purdue starting quarterback Elijah Sindelar is out indefinitely after undergoing surgery Monday to repair a broken clavicle.
Coach Jeff Brohm confirmed the injury, saying Sindelar will miss "an extended period of time" and possibly the rest of the 2019 season.
Sindelar and star wide receiver Rondale Moore both were injured on the same play in Saturday's loss to Minnesota.
Brohm said Moore, a 2018 All-America selection and the Big Ten freshman of the year, will miss at least this week's game at No. 12 Penn State.
