Green, a four-time Pro Bowler, spent most of his two-year career in Houston on the inactive or injured reserve lists.
The Texans released running back Ahman Green and linebacker Morlon Greenwood on Tuesday. It had been speculated that both players would be let go this offseason after battling injuries in 2008.
Green, a four-time Pro Bowler, signed as an unrestricted free agent from Green Bay in 2007. He struggled with knee injuries during his two-year career in Houston and rushed for only 294 yards and three touchdowns in 2007 and 260 yards and two touchdowns in 2008.
This past season, Green was placed on the reserve/injured list on Nov. 25 after spraining his knee at Cleveland in Week 12. At that point, he already was playing as a backup to rookie Steve Slaton, who had been starting since Sept. 21 at Tennessee, when he rushed for 116 yards and a touchdown. The third-round draft pick from West Virginia never relinquished his starting spot.
Green is Green Bay's all-time leader in total yards from scrimmage with 10,870 yards and ranks second on the Packers' all-time rushing list with 8,162 yards, only 45 yards behind Hall of Famer Jim Taylor's total of 8,207.
Greenwood, a third-round selection of the Miami Dolphins in 2001 from Syracuse, signed with Houston in 2005. He put together his best season in 2007, finishing with 118 total tackles (90 solo), good for second on the team behind linebacker DeMeco Ryans. Greenwood was slowed by injuries last season and lost his starting weakside position to rookie Xavier Adibi, who moved into the starting lineup at Indianapolis on Nov. 16.
