The former Michigan quarterback, signed by Pittsburgh as a free agent last month, saw some reps behind center during Tuesday's OTAs, according to ESPN.com. Gardner, who was released by New England prior to joining Pittsburgh, has been projected as a receiver at the NFL level if he's going to stick on a roster.
The Steelers, of course, are no stranger to converted collegiate quarterbacks. Antwaan Randle-El was a starting QB at Indiana, while Hines Ward dabbled as a signal-caller at Georgia.
Before that, Kordell Stewart made the name 'Slash' famous. After serving as the starting quarterback for three seasons at Colorado, Stewart emerged as a playmaker as a receiver in his first two seasons with Pittsburgh. He took over as the full-time starter at quarterback in 1997 and led the team to the AFC Championship game in 2001.
Gardner has little chance of making the Steelers roster as a quarterback with Landry Jones and Tajh Boyd battling it out for the No. 3 spot on the depth chart.
Former Boston College quarterback Tyler Murphy is also trying to make the roster as a receiver.
