Guice (knee) was formally placed on injured reserve Saturday, ESPN's John Keim reports.

EDGE Analysis

Guice won't be available to play this entire season while he recovers from a torn ACL he sustained in Thursday's preseason opener. Given the timing of when the injury took place, the rookie could be fully back in action by the time the Redskins' offseason training program begins next spring.

Guice, who exited Thursday's preseason opener with a knee injury, was diagnosed with a torn ACL on Friday, Adam Schefter of ESPN reports.

EDGE Analysis

This is a devastating break for Guice, who was able to walk off the field under his own power Thursday. With the rookie out of the picture, Washington will now look to Rob Kelley and Samaje Perine to compete for the early-down carries to complement pass-catching specialist Chris Thompson.

Guice (knee) received an initial diagnosis of a sprained MCL, but he still needs an MRI for confirmation, Ian Rapoport of NFL Network reports.

EDGE Analysis

Guice is scheduled for an MRI on Friday after being removed from Thursday's preseason game against the Patriots late in the first quarter. He walked off the field without any help and stuck around on the sideline with his teammates, but he did appear to have a slight limp in the locker room after the game, per Rich Tandler of NBC Sports Washington. Guice had six carries for 19 yards in his NFL debut, with a 34-yard gain wiped out by a penalty on the same play he suffered the knee injury.

Guice (knee) will have an MRI on Friday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Guice was injured during Thursday's preseason game against the Patriots at the end of an impressive 34-yard run that was wiped out by a penalty. He grabbed his left knee after the play, but it wasn't long before he stood up and walked off the field under his own power. Following a brief examination from the training staff, Guice hung around on the sideline with his teammates for the rest of the night. Per Rich Tandler of NBC Sports Washington, Guice had a slight limp in the locker room after Thursday's game, but he didn't have ice or a brace over his leg. The rookie second-round pick dealt with an injury to the same left knee last season at LSU, missing a game Sept. 30 and managing just 121 yards on 37 carries over the following two weeks.

Guice left Thursday's preseason game against the Patriots to be evaluated for a possible knee injury, JP Finlay of NBC Sports Washington reports.

EDGE Analysis

Rob Kelley got the start and the first two carries, but Guice was busy throughout the rest of the first quarter until he came up grabbing his left knee after a 34-yard run that was wiped out by a penalty. He walked off the field under his own power and was walking around the sideline after a brief meeting with the training staff. While the early signs hint at a minor injury, Guice likely will be held out for the rest of the night, finishing his NFL debut with six carries for 19 yards. He was bothered by an injury in the same left knee last season at LSU, but he's been healthy throughout the offseason and into training camp.

Guice won't see the field during Thursday's preseason contest in New England, JP Finlay of NBC Sports Washington reports.

EDGE Analysis

Guice joins Chris Thompson (leg) on the pine, leaving Rob Kelley and Samaje Perine to earn plenty of reps in the exhibition opener. The decision may have been made with an eye on the regular season, when Guice is expected to handle the first two downs with Thompson taking on any and all pass-catching reps out of the backfield. The next opportunity for Guice's first preseason action comes next Thursday, Aug. 16 against the Jets.

Guice is earning praise from coaches for his work in the meeting room, John Keim of ESPN.com reports.

EDGE Analysis

Guice's unexpected slide to No. 59 overall in April's draft seemed to at least partially be a product of his strong personality, though injuries and a lack of pass-catching experience may have also played a role. His effort doesn't seem to be a concern, with Redskins coaches already commenting on his aggressive nature in pass-protection drills and attention to detail in meetings. While Guice still needs to improve his blocking technique, he's shown no hesitation to the dirty work of his position, which helps to explain why he's getting regular run with the first-team offense. Chris Thompson (leg) still figures to get most of the playing time in passing situations, but Guice already seems to be ahead of Samaje Perine in a battle for the lead runner role.

Guice took the bulk of Washington's first-team running back reps at Thursday's practice,John Keim of ESPN.com reports.

EDGE Analysis

Though the team didn't practice in pads Thursday, it's worth noting that Guice displayed some strong cutting ability in the process. The 5-foot-11, 225-pounder fell all the way to pick No. 59 in April's draft, but our bet is that ends up being a major steal for Washington. By the time Week 1 rolls around, look for Guice to head the team's backfield, with Chris Thompson in line to serve in a change-of-pace role. Samaje Perine, Rob Kelley and Byron Marshall are also in the mix, but Guice's combo of speed, power and balance should lead to him getting a solid share of early-down work as a rookie.

Redskins coach Jay Gruden said he views Guice as "more of a first-, second-down banger", ESPN.com's John Keim reports.

EDGE Analysis

Given that he caught only 32 passes in 35 games at LSU, the No. 59 overall pick from April's draft likely would be ticketed for an early down role even if he hadn't landed on a team with Chris Thompson (leg), one of the better pass-catching backs in the league. Boasting 4.49 speed at 224 pounds, Guice instantly becomes the best athlete in Washington's backfield and shouldn't have too much trouble beating out Samaje Perine and Rob Kelley (knee) for a role as the lead runner. Though he may eventually develop into a useful pass blocker and receiver, Guice doesn't figure to get many snaps in passing situations as a rookie.
