Benn, 27, was cut Saturday by the Jaguars, but found himself back in demand following the Wells injury.
He’s has dealt with numerous season ending injuries, most recently last season which was cut short due to a broken collarbone.
Benn has yet to play an entire regular season in his career and hasn’t played in a regular season since 2012 when he was with the Buccaneers.
Wells, 25, missed all of the 2015 season with a dislocated thumb, but was healthy in time for this season’s training camp.
Well’s will miss the the 2016 season after having surgery on that thumb, after re-injuring it.
