DAVIE, Fla. -- Miami Dolphins defensive end William Hayes tore the ACL in his right knee on Sunday in an unusual way.
It happened while Hayes completed a huge third-down sack on Oakland Raiders quarterback Derek Carr, coach Adam Gase said.
"He was trying to not put body weight on the quarterback," Gase said. "His foot got caught in the ground."
According to the new NFL rule change, aa defender laying their body weight on a quarterback after a tackle or sack equals a a 15-yard roughing the passer penalty.
