Trent Murphy was supposed to miss the first four games of the season, now it looks like he'll miss all of the 2017 campaign.

Per a report by NFL insider Ian Rapoport, Murphy tore his ACL in Thursday's preseason game against the Baltimore Ravens.

The Redskins linebacker was suspended four games by the NFL for violating the league's performance-enhancing drugs policy.

Murphy, 26, was second on the Redskins with nine sacks last year, trailing only Ryan Kerrigan.

Murphy has 112 tackles in three NFL seasons.
