Pats release OL Mattes from IR list

The Patriots released offensive lineman R.J. Mattes from the injured reserve list on Saturday.

Mattes, originally a college free agent out of North Carolina State, had two tenures with the Patriots.

He injured his ankle in the team's second preseason game, leading to him landing on the injured reserve list.

The Patriots will need to trim their roster down to 75 players by Tuesday.
