Cam Newton is still perfect this season. Tony Romo might be out for good with the same injury that sidelined him for seven games. Newton got a big boost from a defense that returned two of Romo's three interceptions for touchdowns, and the Panthers ran their NFL-best winning streak to 15 regular-season games with a 33-14 victory over the Dallas Cowboys on Thursday. Romo injured the same left collarbone that sidelined him for all seven games of a losing streak that damaged the playoff hopes for the defending NFC East champion Cowboys (3-8). The 35-year-old with a surgically repaired back said he would have to wait for more test results before knowing if he broke the collarbone again. He was injured in Week 2 at Philadelphia and said the injury had a similar feel this time.Romo was sacked by linebacker Thomas Davis on the final play of the third quarter Thursday in the Cowboys' 33-14 loss to the undefeated PanthersRomo injured the same left collarbone that sidelined him for seven gamesCarolina returned two of Romo's three interceptions for touchdownsThe Cowboys (3-8) lost all seven games that Romo missed with a broken left collarbone before winning in his return at Miami last weekPost-game scans proved inconclusive and Romo will be assessed on Friday
