Per NFL's Ian Rapoport, there was hope Guice had only suffered an MCL injury, but the young running back's walk off the plane "was concerning".
Guice was selected in the second round of the 2018 NFL Draft out of LSU. Liz Loza can relate.
Kelley has earned praise from Jay Gruden, and Perine is said to be looking better than he did last season, when he averaged 3.4 yards per carry and didn't factor much into the receiving game.
Washington will open up the season on the road in Arizona on September 9. Injuries to Week 1 starter Rob Kelley and prolific third-down back Chris Thompson contributed to that, and Guice was expected to be a major part of solving the problem.
Perine had been mentioned as a possible cut earlier this summer, and while that's unlikely to happen now, it should give us an idea as to what the coaching staff thinks of him.
Guice ran with bad intentions in his career with the Tigers, averaging north of 4.0 yards after contact per attempt in each of his first two seasons with the team (2015-16). "Heal up and get ready to take over the league next year". Thompson got 64 carries in his 10 games previous year, and could be looking at a similar number of rushes per game with Guice out for the season.
The team also announced that tight end Manasseh Garner will miss the season with an ACL injury sustained in Thursday night's game.
