New York Jets guard Matt Slauson is being called out by players like Green Bay Packers linebacker Clay Matthews for using a chop block on Houston Texas linebacker Brian Cushing that tore Cushing’s ACL and ended his season.

Slauson’s coach Rex Ryan said there was nothing dirty about the block, which occurred in the second quarter of the Texans’ 23-17 victory over the Jets Monday night.

“I would never question our guys as far as trying to injure someone or try and do something not in the confinement of the rules,” Ryan said on ESPN radio Tuesday. “I would have to say I would definitely question (the flack Slauson is getting), I never saw anything specifically (when) I was just watching our game tape. I’ll say this — we got rolled up a few times in our game, and sometimes in this game you gotta be fortunate to avoid some injury.”

Texans coach Gary Kubiak declined to say if the hit was illegal and said that’s something for the NFL to decide.

“That’s in the league’s hands,” Kubiak said Wednesday. “It doesn’t change the fact that we’re sitting here today having to deal with losing a heck of a player.”

Houston Texans linebacker Brian Cushing faces a possible ACL tear and an end to his season, according to a report Tuesday morning from  NBCSports.com:

A source told PFT’s Mike Florio that the Texans’ medical staff fears Cushing suffered a torn ACL in Monday night’s win over the Jets.

The team will have a better idea today when Cushing receives an MRI on his knee. He was seen limping off the field and into the locker room in Monday’s win against the Jets. New York’s offensive lineman Matt Slauson hit Cushing in the back of the knee, which sent Cushing to the ground in what appeared to be a serious injury. Texans coach Gary Kubiak said he is “very concerned” about the injury, according to Fox Sports:

”I don’t know what happened,” Kubiak said. ”They tell me he cut on a play and his foot might have got stuck in the turf.”

While it’s possible Cushing’s injury may not be season-ending, it appears as if he’ll be out next week when the Texans play the Green Bay Packers on Sunday. The loss would be a significant blow to the Texans, as Cushing has been one of Houston’s more reliable defensemen over the past few years.

Houston Texans linebacker Brian Cushing had an MRI on his knee after it bothered him some during offseason workouts, the team said in a statement, according to a report by Pro Football Talk‘s Mike Florio.

“No, just his knee got sore on him; and I’m going to err on that side this time of year, so we sent him down for an MRI,” Houston coach Gary Kubiak said, via comments distributed by the team.  ”He did come out and watch practice, and it gives some other guys a chance to get some reps.”

Cushing was the NFL’s defensive rookie of the year in 2009. He was suspended for four games the following season after testing positive for steroids. He has never missed a game because of injury.
