Buccaneers waive James Ruffin, sign R.J. Mattes

The Tampa Bay Buccaneers have signed offensive guard R.J. Mattes. The second-year player entered the NFL as an undrafted free agent out of North Carolina State last year, spending most of the 2013 and 2014 offseasons with the New England Patriots. The 6'6", 313 lbs. guard played his college football at North Carolina State, where he protected Russell Wilson and Mike Glennon.

To make room for Mattes, the Buccaneers waived defensive end James Ruffin. The former AFL player spent the past couple of weeks with the Bucs, filling in due to injuries to Da'Quan Bowers and Steven Means.

The Buccaneers have now made 100 roster moves under Lovie Smith, and with final cutdowns just around the corner, they're likely to end up with around 150 roster moves by the time the season starts.They have to cut down to 75 players on Tuesday, August 26 and to 53 players on Saturday, August 30.

Correction: As Greg Auman points out, the Bucs have actually made 114 roster moves since Lovie Smith became head coach. Not sure where my count messed up, but it did.
