The Atlanta Falcons released veteran running back Steven Jackson on Thursday, adding to a growing list of rushers who have been or will be released before free agency begins March 10.

Jackson, 31, signed with the Falcons in 2013 after spending his first nine years with the St. Louis Rams. Over the past two seasons, he rushed for 1,240 yards and 12 touchdowns while battling injuries — he missed four games in 2013 and one in 2014.

Jackson was due to make $3.75 million in the final year of his contract with the Falcons — money they will recoup under the salary cap.

Jackson was the Rams’ first-round pick in 2004 and surpassed 1,000 rushing yards in all but his rookie season, leaving as the franchise leader with 10,138 yards. His 11,388 yards rank 16th in NFL history.

Jackson joins a number of veteran running backs who have become free agents ahead of the start of the league year March 10: Chris Johnson, Reggie Bush, DeAngelo Williams and Peyton Hillis.
