Trent Murphy has been suspended by the NFL for the first four games of the 2017 season due to a PED violation.
Murphy's looming suspension had been reported last month, but he was appealing the decision.
Entering his fourth season, Murphy is coming off his best year in 2016, with nine sacks as the Redskins' third outside linebacker behind Ryan Kerrigan and Preston Smith.
