EUGENE, Ore. (AP) -Oregon running back Jonathan Stewart underwent surgery earlier this week to repair a right toe injury he suffered in November.

Recovery is expected to take four to six months, preventing Stewart from working out for scouts as scheduled at Oregon's second pro day and potentially hurting his stock heading into the NFL draft April 26-27.

But his agent, Ben Dogra, said the 45-minute procedure went smoothly and Stewart would be ready for training camp in July.

He is expected to be a first-round draft pick.

``At the same time there's nothing you can do about it,'' said Stewart. ``So there's no need to stress about it.''

He sustained the turf toe injury against Arizona on Nov. 15 and it hadn't healed on its own. NFL general managers and scouts recommended Stewart have the surgery now rather than risk missing training camp or games, Dogra said.
