The Washington Redskins suffered a jarring blow when rookie running back Derrius Guice was lost for the season because of a torn ACL sustained in Thursday's preseason opener against the New England Patriots.
Results of an MRI exam confirmed the severity of the injury to Guice, the Redskins' second-round pick in the 2018 NFL Draft.
Washington also announced Friday that tight end Manasseh Garner will miss the season after suffering a torn ACL in Thursday's game.
"Both players are expected to make a full recovery and are looking forward to playing in 2019," the team said in a statement.
Washington was expecting big things from Guice, who rushed for 1,251 yards and 11 touchdowns last season at LSU. He was even better as a sophomore, piling up 1,387 rushing yards and 15 touchdowns.
Guice finished with only 19 yards on six rushing attempts in the Redskins' 26-17 loss, but it was a play that didn't count that drew the most oohs and aahs -- and resulted in the injury.
The 5-foot-11, 225-pound Guice broke off a highlight-reel 34-yard run that was negated by a penalty.
Guice made a quick cut-back to break into the open, spun away from one defender and then stiff-armed another would-be tackler, but he was slow to get up and hobbled to the sideline.
Following the game, the rookie downplayed the injury, saying, "I'm good," and, "All is well" in the locker room.
"I can walk fine," Guice told the Washington Post. "I guess, at the back end of the play when I was still (fighting), my feet just kind of planted weirdly on the turf and my knee just hyperextended a little bit. It's fine."
Redskins coach Jay Gruden was hoping for the best after Thursday's game while telling reporters that Guice was scheduled for an MRI exam.
"Hopefully, it's nothing, but if it is, I'm sure Derrius will rehab it and get himself back," said Gruden, who revealed that Guice had lobbied for a heavy workload entering his NFL debut. "He's a guy that doesn't like to carry the ball three times. He needs to carry the ball 15 times. He actually told me before the game, 'If you're going to give to me three times, don't even put me in.'"
