Jameis Winston loses his cool, headbutts player

Jameis Winston has been a huge part of the Buccaneers' win streak, but he hurt his team in a big way during the second quarter on Sunday.

With the Buccaneers driving inside Dallas' 10-yard line, Winston lost his cool and headbutted Cowboys linebacker Justin Durant after a five-yard loss.

The officials didn't miss it either. Winston was hit with a 15-yard unnecessary roughness penalty, which dropped Tampa Bay back to the 28-yard line.

Tampa Bay had to settle for a field goal.
