What does Cowboys' McBriar move mean?

Bit of a last-minute roster surprise, as the Dallas Cowboys put their excellent punter, Mat McBriar, on injured reserve Saturday, the day before they will play the New York Giants in a game to decide the NFC East champion. McBriar has been dealing with left foot problems all season, but said this week he felt good enough to punt Sunday. Instead, Chris Jones will handle punting duties for Dallas on Sunday and, if they win, in the playoffs.

In another move, the Cowboys added quarterback Chris Greisen from the practice squad. That means they'll have three quarterbacks available Sunday night, and that's what raises the eyebrow a little bit.

Tony Romo, the Cowboys' starting quarterback, injured his right hand in last weekend's loss to the Eagles. Though he's practiced all week, and I'm 100 percent certain he'll start Sunday's game, you have to wonder if the move with Greisen means the Cowboys are at least a little bit concerned about Romo's ability to make it through the game all the way. Stephen McGee is the backup quarterback and played in Romo's place last weekend, but if Romo were unable to throw, they'd theoretically be left only with McGee, and would need someone to step in if he got hurt.

Of course, Greisen could also have been called up to serve as Dan Bailey's holder on field goals, since Romo did that the last time regular holder McBriar was unable to play. We will see, but the mystery surrounding Romo and his throwing hand appears as though it will linger at least a little bit into the most important game of the Cowboys' season.
