Romo has been limited in practice this week after slamming his right hand on the helmet of Eagles defensive end Jason Babin on Dallas' first possession last Saturday.
He left the game and has been battling swelling, but Cowboys owner Jerry Jones reportedly told a Dallas-area radio station Friday morning that he expects the quarterback to play "at full strength," according to ESPN.
X-rays taken on Romo's hand Saturday were negative and it would seem unlikely that he will miss the game with a playoff berth on the line.
The winner of Sunday's game will capture the NFC East title and earn a No. 4 seed, while the loser will be eliminated from playoff contention.
