Following the 2014 season, Raiders outside linebacker Sio Moore had what Reggie McKenzie is calling a "major" surgery on his hip. He injured the hip last season in the week 13 game against the Rams in St Louis and was hobbled by it the following week against the 49ers before being shut down for the final three games of the season.

McKenzie spoke with the media at the scouting combine Wednesday where he pointed out Sio Moore would not be participating in any of the team's offseason workouts, though he is expected back by training camp.

"He had major surgery, so it's going to take him awhile to get back," McKenzie said as reported by CSN Bay Area. "We're not going to have him push through just to have him ready for the start of OTAs. We're not going to do that. We'll be smart about it. We're going to let him rehab and get strong. Barring any setbacks, he should be ready by training camp."

Last offseason, Sio lost first team reps at weakside linebacker to Miles Burris. That was because Sio was transitioning to the weakside after playing strongside linebacker as a rookie and Burris was ahead of him in learning defensive alignments.

Now Burris will be expected to take those reps again with Sio on the sideline recovering from his surgery.
