Dolphins defensive lineman William Hayes is out for the season, coach Adam Gase told reporters on Monday morning. Hayes suffered a torn ACL while sacking Raiders quarterback Derek Carr. 
“He was trying to not put his body weight on the quarterback and that happened,” Gase said.
Hayes was traded to Miami in the 2017 offseason following five years with the Rams organization. The 33-year-old proceeded to play in ten games for the Dolphins, compiling 19 tackles and a single sack. This was a far cry from his performance with the Rams, as Hayes collected at least four sacks each season between 2012 and 2016. Despite the underwhelming numbers, Pro Football Focus was fond of his performance in 2017.
This year, Hayes was off to a productive start with two sacks through three games in a part-time role. Unfortunately, he’ll be shelved for the rest of the year before hitting free agency in March.
