UCLA offensive tackle Simon Goines will not participate in training camp due to an undisclosed medical condition, head coach Jim Mora said on Monday.

The redshirt junior has struggled with several leg injuries throughout his career, and missed all of the 2014 season in an attempt to get fully healthy. However, Mora said that the lineman’s condition is not related to his past injuries, and also that it was not life-threatening.

Without Goines, who started 20 games in his first two seasons, UCLA will rely on Caleb Benenoch at starting right tackle. In addition to senior center Jake Brendel and junior left tackle Conor McDermott, the Bruins’ first string currently consists of left guard Kenny Lacy and right guard Alex Redmond.

Also absent from the first day of camp were redshirt sophomore running back Craig Lee (academics), tight end Chris Clark (didn’t dress due to mononucleosis), and receiver Cordell Broadus. Broadus was granted a couple of days off due to a personal issue.
