NFL Network's Mike Mayock is reporting that Oregon RB prospect Jonathan Stewart may need surgery on his big toe, which would leave him sidelined for 4-6 months. You can see the clip at about the 1:45 mark here.
Mayock references two NFL GMs as sources for speculation that Stewart will possibly need the surgery, so the story appears to have some legs. In which case, it's conceivable that Stewart could start to tumble down the draft boards. I think we're in a wait and see pattern for now.
Rotoworld should have a news blurb up on this soon, so I'll copy and paste that as soon as I can.
Update---here's Rotoworld's take:
NFL Network's Mike Mayock reports that Oregon RB Jonathan Stewart may need surgery on his big toe. The procedure would keep him out four to six months.
Stewart suffered a turf toe injury in November and didn't miss any games. He also ran the forty at the Combine, but performed no shuttle or cone drills. In the meantime, he had MRIs done and doctors recommended he undergo surgery. Individual teams will evaluate whether surgery is required. Expected to be a first-round pick, his stock will fall dramatically with any team that doesn't medically clear him.
Another update--from Rotoworld:
NFL Network's Adam Schefter reports Oregon RB Jonathan Stewart underwent surgery on his big toe Wednesday. He'll be out four to six months.If Stewart heals quickly, he'll have a chance to be ready before the start of training camp. Still, Stewart will miss all pre-camp work and his draft status will likely be affected severely. It's a somewhat similar situation to Adrian Peterson's in 2007, but Stewart doesn't have the same talent or upside. It wouldn't be a surprise to see him fall to round two.
