Stop me if you've heard this before.
Washington Redskins running back takes advantage of a big preseason opportunity and rips off a run of more than 30 yards, causing coaches, teammates, media and fans to salivate at his potential.
Minutes later, he is being attended to by the team's medical staff for a leg injury.
He was wrong. MRI results the next day showed that his ACL was torn and that he would require season-ending surgery.
History threatened to repeat itself in the second preseason game, as Samaje Perine got the start and ripped off a 30-yard run. On the tackle that ended the run, Perine's foot caught in the turf and twisted, leaving him to hobble to the sidelines. He was later taken into the tunnels and evaluated for an ankle injury. Some time later, he was ruled out of returning to the game, which was a certainty in the preseason.
It is unclear if he would have gritted through such an injury in the regular season, but the decision was made easy on a Thursday night in August.
He has a chance to re-write that reputation, but only if he's healthy. Perine and the Redskins have plenty of time to overcome a minor ankle injury, but first we need a diagnosis. Head coach Jay Gruden's Friday press conference has a new layer of intrigue.
