San Francisco released Turay on Tuesday, Jeremy Fowler of ESPN.com reports.
Turay racked up a respectable nine tackles and 5.5 sacks in 13 games with the Colts, but he couldn't secure a situational depth role on the 49ers' initial 53-man roster. The 27-year-old defensive end seems like a fair candidate to draw interest elsewhere in the league, if not to rejoin San Francisco at a later date.
