Rest for Aaron Rodgers, Donovan McNabb

Two NFC North quarterbacks sat out practice Monday, but I don't think there is much to read into either instance.

Green Bay Packers quarterback Aaron Rodgers sat out practice Monday because of a foot strain that "flared up on him this morning," coach Mike McCarthy told reporters. Meanwhile, the Minnesota Vikings gave quarterback Donovan McNabb a day of rest amid indications he'll be held out of Thursday's preseason finale against the Houston Texans.

The Vikings are expected to split the quarterback duties Thursday between backups Joe Webb and Christian Ponder, who are vying for the No. 2 job behind McNabb. Most, if not all, Vikings starters could sit out the game.

The Packers' situation with Rodgers is a little less clear. Rodgers showed no outward signs of injury in last Friday's preseason game against the Indianapolis Colts, during which he threw for 204 yards in two quarters of action. He broke his foot in 2006 and has since spoken of a certain style of shoes that help relieve pain in his feet.

Still, there are no indications that Monday's absence was anything other than a good opportunity to give Rodgers a breather before the regular season routine ramps up. McCarthy said he was "just being cautious" and added: "If it was up to him, he would have practiced today. I'm just being smart with him."

McCarthy didn't rule out Rodgers for Thursday's preseason finale against the Kansas City Chiefs, but at this point it wouldn't make much sense to play him.
