Rebels' Williams doubtful against Georgia

OXFORD, MISSISSIPPI - Mississippi tailback Robert Williams is doubtful for Saturday&#39;s game against Georgia after aggravating an ankle injury during practice earlier this week. <br> <br> The Rebels&#39; leading rusher has missed the last two games because of a separated shoulder. He missed two games earlier this season with a sprained ankle. <br> <br> Vashon Pearson, Ronald McClendon and Tremaine Turner have been used in Williams place, but Ole Miss has received little production from its running game when Williams has not played. <br> <br> Turner missed last week&#39;s game against Auburn because of a sprained knee, but is expected to play Saturday. <br> <br> ``Robert&#39;s probably not going to play, but Tremaine looks like he&#39;s all the way back,&#39;&#39; Ole Miss coach David Cutcliffe said.
