Texans waived WR Derrick Mason. This might just about do it for the rapidly declining veteran. Acquired from the Jets in early October, Mason made just six catches in seven games, and only three after Week 6. He was a healthy scratch in Week 13. Mason has simply lost the ability to separate, and didn't show enough to stick in the slot. If he's played his final game, he'll end his sterling 15-year career with 943 catches (12th all time) for 12,061 yards (18th all time) in 230 games.
