Shepard, a receiver with the New York Giants, was penalised $10,000 for leaving the game against the Dallas Cowboys in Week 3 after hitting quarterback Daniel Jones.
The Giants eventually suffered a 23-16 defeat.
Shephard's season-ending ACL tear occurred on his team's final attacking possession, which is even more tragic for him.
The NFL must, of course, apply the rules consistently regardless of the specific situation.
But Shepard, who will now miss the remainder of the 2022 season after having his 2021 season cut short by an Achilles tear that he also sustained in another loss to Dallas, finds little solace in that.
American football wide receiver Sterling Clay Shepard plays for the National Football League's New York Giants.
Oklahoma was Shepard's collegiate football team.
During the 2016 NFL Draft's second round, the Giants selected Shepard.
Shepard was given a four-year, $5.94 million contract by the Giants on May 6, 2016, which included a $2.52 million signing bonus and a $3.24 million guarantee.
