The Chicago Bears kicked off minicamp Friday with several notable players watching from the sidelines. The team announced that tight end Brandon Manumaleuna and receiver Earl Bennett underwent minor offseason knee operations, which kept Manumaleuna from participating in the workout and limited Bennett. "Don't have a timetable [on Manumaleuna's return] per se, again we've got OTAs coming up," Bears coach Lovie Smith said. "It's just a little minor scope with him. Hopefully we can get some of those guys, Earl Bennett and players like that, back before long." With Manumaleuna sidelined, Greg Olsen and Desmond Clark both took reps with the first team at tight end Friday morning. Bennett sounded optimistic that he would soon be cleared for full participation. http://sports.espn.go.com/chicago/nfl/news/story?id=5207465
