GREEN BAY, Wis. -- Defensive tackle B.J. Raji has been upgraded to probable for Green Bay's game against the Minnesota Vikings on Sunday night.

The move gives the Packers hope that they'll have one of their top run-stuffers available to contain NFL leading rusher Adrian Peterson.

Raji missed last week's loss against Arizona with a concussion.

The Packers also upgraded linebacker Mike Neal to probable after Saturday's practice. Neal has been bothered by a sore hip.

But Green Bay could be without cornerback Sam Shields for a third straight game because of a concussion. Shields was downgraded to doubtful.

Two other key players remain questionable for the Packers: left tackle David Bakhtiari has an ankle injury, while defensive tackle Mike Daniels has a groin injury.
