CHICAGO (Reuters) - Green Bay Packers quarterback Aaron Rodgers had limited practice with his team on Thursday, raising hopes he could return from concussion to play against the Miami Dolphins on Sunday.
Rodgers suffered the concussion after being hit late in overtime in the 16-13 loss at the Washington Redskins four days ago.
"Aaron has gone through the protocol of all of the medical testing that's involved," Packers head coach Mike McCarthy told reporters. "We would not have put him on the field today if he did not pass that.
"But it's like anything. There may be potentially a setback or something. That's why we limited him today at practice. We're going to watch him closely, just like we always do.
"He felt fine and I communicated with him during the course of the practice. But it's Thursday and I've never made any decisions on injured players coming back on Thursday."
New NFL regulations on concussion mean Rodgers will have to go through an independent doctor's visit before he is given the green light to play again in the league.
"As far as his availability for the game, it will really still come down to the medical staff fully clearing him," McCarthy said. "He was limited today and we'll see how he feels tomorrow.
"I thought Aaron practiced well today. He threw the ball well."
The Packers, who have several other players sidelined through injury, are 3-2 in the NFC North behind the 4-1 Chicago Bears.
