Redskins' Robert Davis suffered multiple ligament damage in knee, sources say

RICHMOND, Va. -- The Washington Redskins have suffered yet another season-ending injury, as wide receiver Robert Davis suffered multiple ligament damage to the outside of his right knee in practice Saturday, according to multiple sources.

Coach Jay Gruden on Sunday confirmed that Davis would undergo surgery and miss the 2018 season. Davis will be sidelined nine to 12 months, Gruden said.

Davis, who also suffered a broken tibia, becomes the third Washington player to be lost for the season, with rookie running back Derrius Guice headlining the list of casualties. He tore his ACL in Thursday's preseason loss to the New England Patriots. Tight end Manasseh Garner also tore his ACL in that game.

Davis was fighting for a backup job; he caught three passes for 35 yards against the Patriots.

He was injured in practice Saturday during a 7-on-7 drill while jumping for a pass against cornerback Danny Johnson. Davis struggled to get off the ground, then was helped to the sideline, where he was soon placed on a cart and driven into the facility. The sixth-round pick in 2017 spent most of last season on the practice squad but did appear in one game.

NFL Network first reported the nature of Davis' injury.
