Steve Smith had 107 receptions for 1,220 yards and seven touchdowns with the Giants in 2009.
Three years later, the receiver has endured microfracture knee surgery, a failed move to Philadelphia and a second trip to injured reserve.
"First off, he's a very first-class young man," coach Jeff Fisher said. "Overcame a difficult situation with his knee. The guy had an extraordinary workout and has a chance to get back where he was in 2009."
