The Falcons have placed defensive Jack Crawford on injured reserve with a biceps injury, the club announced today.

Crawford, whom Atlanta signed away from the Cowboys this offseason, is now the third Falcons defensive lineman to go down with injury in recent weeks. Star edge rusher Vic Beasley is still working his way back from a hamstring issue, while Courtney Upshaw may be close to returning from an ankle ailment. Crawford, for his part, had played on 101 defensive snaps this season but graded as just the No. 87 interior defender among 100 qualifiers, per Pro Football Focus.

With Crawford sidelined, the Falcons auditioned defensive ends Devin Taylor, Jonathan Woodard, Sterling Bailey, Nicholas Williams, Pat O’Connor, plus linebacker Lavar Edwards, on Monday, according to Vaughn McClure of ESPN.com. Atlanta is on the hunt for defensive line reinforcements, and its workout session comes as no surprise given that head coach Dan Quinn indicated that he and general manager Thomas Dimitroff would soon discuss adding help to their front four.

Taylor, 27, offers vast experience, as the former fourth-round pick appeared in 61 games (18 starts) for the Lions over the past four seasons. While he’s posted 15 sacks during his NFL career, PFF wasn’t complementary of Taylor’s performance in 2016, ranking him as the second-worst defensive end in the league. Taylor signed with the Giants in May but didn’t make it through final cutdowns, and has since worked out for the Vikings.

The Falcons’ defensive front, which currently includes Grady Jarrett, Dontari Poe, Brooks Reed, Adrian Clayborn, Derrick Shelby, and first-round rookie Takkarist McKinley, hasn’t played all that well in 2017, as the unit ranks 21st in adjusted sack rate and 25th in adjusted line yards, per Football Outsiders.
