Just because it's a holiday doesn't mean there's not some sniping going on between the Lions and Texans. Detroit linebacker Travis Lewis and Houston receiver Keshawn Martin got into an argument on a punt return, eventually having to be separated.
As the scuffle was being broken up, Martin decided to go ahead and throw the ball at Lewis. Right in front of the ref.
Rejected.
Predictably, Martin was penalized, a 15-yard penalty for the Texans. The second guy always gets caught!
