Coach Tyrone Willingham told the Pac-10 media today that the team is expecting to get the results of Chris Polk's MRI this afternoon. Willingham said that the freshman tailback is doubtful for this week, but also acknowleded that Polk's season could be in doubt.
"We'll be reading his MRI this morning and it kind of looks doubtful that he'll be ready this week and it could even be by the time we get to the afternoon it could be long-term," Willingham said.
Asked if that meant he might miss the rest of the season, Willingham replied: "Could be."
True freshman David Freeman is atop this week's depth chart at tailback.
Willingham also said raised the possibility of some resolution regarding linebacker E.J. Savannah, last season's leading tackler who has been out since the start of fall camp due to academic and other unspecified issues.
"There are some developments that are taking place that maybe by the end of the day I might be able to give you some more precise information on that," he said.
