According to Steve Wyche of NFL.com, a team source said Romo's hand has been healing and he isn't expected to be limited.
Given the Cowboys are battling for the NFC East and a playoff berth on Sunday against the Giants, that's certainly a good sign.
Romo threw just two passes before injuring his right hand against the Philadelphia Eagles in Week 16, banging it on a defender's helmet as he completed his throwing motion. He had tossed for eight touchdowns and zero interceptions in his previous three games.
The Cowboys are going to need the Romo from those three games instead of the one who has been wildly inconsistent throughout his career. The Cowboys not only face a Giants team that just blasted the New York Jets, 29-14, they have to march into the hostile MetLife Stadium.
Will Romo's bruised throwing hand affect him on Sunday?
The Giants defense does most of its damage because of the pressure defenders put on the quarterback. The Giants have racked up 41 sacks this season, sixth in the NFL, and defensive end Jason Pierre-Paul has had 15.5 of them.
Pressuring Romo and ensuring he takes some hits in this game could help the Giants pull away from the Cowboys and go on to the playoffs.
Then again, Romo has shown in the past that he can make poor decisions without any pressure, so it all depends on which Tony Romo shows up on Sunday.
One thing's for sure, though: He will show up.
