Cowboys tight end Jason Witten did not practice with the team for a second day in a row Thursday.
Witten suffered a broken rib in Sunday's game against Tampa Bay and says he feels every breath he takes because of the injury.
It's made sleeping difficult for the Dallas Cowboys tight end, and doctors have told him that it could be three or four weeks before his side will feel any better.
But Witten still hopes to play Sunday against the NFC East-leading and rival New York Giants.
Witten was in shorts and doing conditioning drills on with a team trainer at Valley Ranch.
Witten's the NFC leader with 46 catches. He says he'd like to get some practice reps this week, but he still describes himself as a game-time decision.
The Cowboys (5-3) lost three of four games before their 13-9 victory Sunday over Tampa Bay.
Their offense is also without quarterback Tony Romo, who has a broken pinkie, and guard Kyle Kosier with an injured foot.
The Cowboys are also missing several injured defenders.
