Jason Witten scored a touchdown and handed the football to Marc Colombo so the burly offensive lineman could spike it. Then they leaped and bumped chests, with Colombo losing his balance on the landing and tumbling across the end zone. Pretty silly, eh? The Tennessee Titans will be laughing about it for a long time. A penalty for excessive celebration pushed back the kickoff and Tennessee's Marc Mariani followed with a long return, setting up a 1-yard touchdown by Chris Johnson with 3:28 left in the fourth quarter. That gave the Titans a 34-27 victory Sunday over the Dallas Cowboys in a game they were struggling to put away. http://scores.espn.go.com/nfl/recap?gameId=301010006
