PITTSFORD, N.Y. -- The Buffalo Bills are working out defensive lineman Red Bryant and outside linebackers/defensive ends Marcus Benard and Quentin Groves on Monday, a source told ESPN NFL Insider Adam Caplan.

The workouts come one day after the Bills revealed that defensive end Jarius Wynn suffered an ACL injury in last Friday's preseason loss, which could likely keep him out for the entire season. The Bills have also experienced a rash of injuries along their defensive line, with defensive tackle Kyle Williams (quad) and defensive end Alex Carrington (shoulder) sitting out Monday's practice.

Bryant, 31, is a 323-pound defensive tackle who has played for the Seattle Seahawks (2008-2013) and Jacksonville Jaguars (2014). He signed a five-year, $35 million deal with Seattle in 2012 but was released for cap purposes after the 2013 season.

Bryant signed a four-year, $19 million deal with the Jaguars before last season. He started all 16 games before being released in March.

Benard, 30, is a 6-foot-4, 256-pound edge rusher who has played for the Cleveland Browns (2009-2011) and Arizona Cardinals (2013-2014). His career was interrupted by a motorcycle crash in 2011 in which he was thrown 241 feet, breaking his arm.

Groves, 31, is a journeyman edge rusher who has spent time with five teams since being drafted in the second round in 2008.
