The Patriots tried out veteran defensive linemen Frank Kearse and George Johnson, according to the National Football Post.
Kearse was taken by the Dolphins in the seventh round of the 2011 draft out of Alabama A&M. He was released by the Panthers before the start of this season.
Johnson -- surprise, surprise -- is a Rutgers product who has played for the Buccaneers and Vikings.
That the Patriots tried out two d-linemen is not necessarily a sign that they are close to acquiring a new player. NFL teams hold tryouts throughout the season for players at numerous different positions as a way to keep tabs on available players in case they're needed for depth.
However, with defensive linemen Vince Wilfork (Achilles, out for the season) and Tommy Kelly (knee, missed Week 6) banged up, the Patriots could be in the market for help on the defensive line.
Defensive tackle Armond Armstead is eligible to begin practicing this week. He has been on the NFI/reserve list since before the start of the regular season.
