Through the first quarter and a half of the Houston Texans-New York Jets game, Texans linebacker Brian Cushing was everywhere on the field. He had three tackles and two assists, and as usual, he was tough to stop.

There are times when opposing offenses use questionable tactics to stop such dominant defenders, and that appeared to be the case when the Jets called a handoff to running back Bilal Powell with 10:36 left in the second quarter. Cushing was looking to make a play, but guard Matt Slauson appeared to roll up on Cushing, and the linebacker left the field and went to the locker room with a knee injury. It was revealed after the game that Cushing may have a torn ACL.

"I don't want to jump the gun here," Texans head coach Gary Kubiak said after the game,
"but obviously, we're very concerned."



The difference between chop blocks and cut blocks are tough to discern at times, but ourerstwhile guest columnist and former Texans defensive lineman Seth Payne pointed out the difference on the play in no uncertain terms.

"Before somebody makes a misguided statement, there is a difference between a legal zone blocking cut and what Jets OG seemingly did to Cushing," Seth said on his Twitter account. "If it's what it looked like, that block was an either illegal roll up block or clip, depending on the proximity to the line of scrimmage. Debatable whether that was "close line play." Regardless, blocking from behind and below the knee constitutes a clip even in close line play."

Green Bay Packers star linebacker Clay Matthews, a teammate of Cushing's at USC, was similarly unimpressed.



"I mean, they protect the offense. That's kind of what they do," Texans defensive tackle J.J. Watt told USA Today. "It's a tough situation. I mean, I understand. Football's a rough game, and I haven't seen the play so I can't comment on the play. But it's a tough game.*Hopefully it was a legal play because you hate illegal plays, especially when players are injured. That's not what you want."

The block, which certainly looked like an example of the illegal chop, was uncalled by the crew led by referee Scott Green.

From the St. Petersburg Times in 2004:

There is a gray area between the legal cut block and the illegal chop block. The cut block occurs when a player (usually an offensive lineman) blocks another (usually a defensive lineman) below the knees with his helmet in front of the player. The chop block occurs when the same block comes from the side or the back, or when the defensive player is engaged with another offensive player and therefore defenseless.
We'll see how Cushing fares, and it will certainly be interesting to see how the NFL, which has professed an increased interest in player safety over the last few years, reacts to this.
