Smith (knee) remains unsigned while rehabbing from a season-ending injury, Greg Auman of the Tampa Bay Times reports.
Smith had some success as an occasional big-play threat for the Falcons in 2013 and 2014, but a combination of injuries and age have sapped his explosiveness. Even if he returns to full health at some point this offseason, the 31-year-old may find it tough to catch on with a team that gives him a real shot to earn a roster spot. He had 10 carries for 47 yards and six catches for 77 yards in three games with Tampa Bay last season.
