"With Ryne Robinson still recovering from a leg injury and no apparent replacement in sight as the Carolina Panthers' kick returner, coach John Fox might be thinking about giving rookie Jonathan Stewart a try.

Fox wouldn't say whether that might come in the Panthers' final exhibition Thursday against the Pittsburgh Steelers.

"I can't put a time frame on it," said Fox. "(Stewart) was healthy enough to do it (Saturday against the Washington Redskins), but we just didn't feel it, so we'll wait and see."

Ricardo Colclough was solid, if not spectacular, against the Redskins, returning two kickoffs for a 30.5 average, with a long return of 37 yards.

"We're a little nicked there," said Fox. "I think eventually we'll take a look at Stewart."

Stewart, a No.1 draft pick, returned kicks in college at Oregon.

Jason Carter has been returning punts in Robinson's average. He returned seven for a 13.3 average Saturday, including a 30-yarder.

"We've got a couple of question marks as returners both in the punt game and the kickoff," said Fox."
