The NFL’s revised rule on preventing defenders from sacking quarterbacks with the bulk of their body weight was intended to keep quarterbacks healthy. But Miami Dolphins head coach Adam Gase said he believes one of his defensive linemen is now out for the season after trying to adapt to the rule.

Dolphins defensive end William Hayes tore his anterior cruciate ligament, Gase confirmed Monday in a press conference. Gase said the injury was sustained on a play in which Hayes was trying to avoid drawing a penalty flag.

“He will be out for the season,” Gase said. “He tore his ACL on that sack. He was trying to not put body weight on the quarterback. His foot got caught in the ground.”

The play happened on a sack in the second quarter of Miami’s 28-20 victory Sunday against the Oakland Raiders. Hayes charged on Oakland quarterback Derek Carr, who appeared to give himself up. Hayes looked as though he tried to roll off of Carr to avoid landing on top of him with his body weight. Hayes’ cleats then got caught in the turf as his body weight crashed to the ground.

The revised rule was approved this offseason, perhaps in large part due to a hit last year on Green Bay Packers quarterback Aaron Rodgers in which Vikings linebacker Anthony Barr landed on the two-time MVP and broke his collarbone.

In a tweet Monday responding to news of Hayes' injury San Francisco 49ers cornerback Richard Sherman ripped the new rule.

“They don’t care about the rest of us getting hurt,” Sherman wrote. “Long as the QB is safe.”

Hayes, 33, was in his 11th season in the NFL and had collected four tackles and two sacks for the 3-0 Dolphins.

“I mean, it hurts,” Gase said. “He’s one of our leaders, probably one of the best guys in the locker room, probably our best run defender. That’s going to be a tough one for us to swallow.”
