Dallas Cowboys quarterback Tony Romo "most likely" suffered a small fracture in his left collarbone in a loss to the Carolina Panthers 33-14 on Thanksgiving Day, according to a report from Mike Florio of Pro Football Talk. Romo is reportedly done for the 2015 season, according to Ed Werder of ESPN.

Romo said after the game that the collarbone injury feels very similar to the one he suffered during week two against the Philadelphia Eagles, and is expected to get a CT Scan on Friday, according to NFL reporter Desmond Purnell. Cowboys head coach Jason Garrett said after the game that the X-rays were inconclusive.

"So we don't know that much at this point. We'll have further tests tomorrow and we'll see what those show. So taking it day-by-day, don't know much right now. He (Romo) knows it better than anybody else. Again the x-rays were inconclusive. We'll get more tests in the morning," Garrett said, via Purnell's Twitter account.

The Cowboys franchise quarterback suffered the injury in the third quarter after being sacked by Panthers linebacker Thomas Davis. Romo injured the same shoulder when Eagles linebacker Jordan Hicks landed on him after an incomplete pass in week two. Romo missed seven games following surgery, and the Cowboys failed to win a game without him.

Although Romo was expected to save the Cowboys season, he had done little in his return with two touchdowns to five interceptions in less than two games. Romo was 11-for-21 passing for 106 yards with no touchdowns and three interceptions on Thanksgiving. Panthers linebacker Luke Kuechly stole back-to-back interceptions from Romo, one of which he returned for a touchdown, as the Cowboys quarterback looked to be forcing passes.

The Cowboys have now fallen to 3-8 on the season, and although the NFC East is weak this year, Dallas is a long shot to make the postseason. More information is expected to come on Romo's collarbone Friday, but it looks like the Cowboys star quarterback is done for the season.
