PHILADELPHIA -- Eagles quarterback Michael Vick likely will miss at least another game after reinjuring his left hamstring in Sunday's loss to the New York Giants, coach Chip Kelly said Monday.

Kelly, who typically does not reveal much about injuries, said he did not know the results of the MRI that Vick underwent Monday.

Vick's injured hamstring is not as serious as the original strain, league sources told ESPN NFL Insider Ed Werder. Vick will be evaluated weekly.

Kelly said Monday he would proceed as though Vick would not be available for Sunday's game against the Oakland Raiders -- and perhaps longer.

"Mike didn't seem like he was going to be ready this week," Kelly said. "He felt like, the first time, that he was going to be back after the [Oct. 6] Giants game.

"This is the first time I've talked to him where he thought he may be out. We'll see after we sit down and visit, after we get the final [MRI] results."

Kelly said Vick was "day to day" after the original injury. After Vick lasted less than one half upon his return Sunday, Kelly said the original prognosis was for Vick to miss 10 to 14 days.

Meanwhile, Nick Foles, who left the Oct. 20 game against the Dallas Cowboys with a concussion, was cleared to return to practice Tuesday after meeting the NFL's concussion protocol.
