Boilermakers coach Jeff Brohm told reporters Wednesday that Bailey sustained the injury in a non-contact portion of Tuesday's practice. The fifth-year senior will undergo surgery in several weeks. Bailey had knee surgery early in his career and had hip surgery this past offseason.
"He's been a tremendous player for us and worked extremely hard in the offseason to overcome a hip surgery," Brohm told reporters. "He was getting ready to have an outstanding year."
Bailey, a co-captain, has started 40 games for Purdue, including the first two this season. He has 14 tackles this season, including two for loss and a sack. In his Purdue career, Bailey has recorded 327 tackles, including 28 for loss, and 13.5 sacks, to go with six interceptions, two forced fumbles, 13 passes defended and a fumble recovery.
Brohm said Bailey could decide to apply for a sixth year of eligibility.
Purdue resumes play Saturday night when it hosts TCU at Ross-Ade Stadium.
