Tony Romo tried to get back into the game after sustaining an injury in the second quarter of Monday night’s Cowboys-Giants game. The training staff had none of it.

They were right to do so as Romo suffered a fractured clavicle when he was hit by Giants linebacker Michael Boley.

The injury should keep him out at least six-to-eight weeks, according to owner and general manager Jerry Jones. Romo will undergo an MRI to further explore the extent of the injury, reports the The Dallas Morning News.

As a result of Romo’s injury, Jon Kitna will be under center until at least December.

“I’m staying optimistic,” said Romo, whose Cowboys are 1-5 with 10 games remaining. “This football team has a lot of high-character guys, a lot of competitive individuals who aren’t going to give in to a tough situation.”
