Tony Romo is "done for the season" after reinjuring his left collarbone.
Tests on Thursday were inconclusive but a CT scan on Friday revealed a hairline fracture. No surgery will be required for the injury.
Romo said the feeling he had after being sacked by linebacker Thomas Davis was "similar" to what he felt when he broke the collarbone in a Sept. 20 win over the Philadelphia Eagles.
"Going to the ground you could hear something happen," Romo said. "You're just disappointed and feel like I don't know what is going to happen. We'll see."
