Shanahan unsure on McNabb for Redskins opener

[August 30, 2010]  ASHBURN, Va. (AP) -- It could be a smoke screen or just a cautious assessment of his quarterback's health, but Mike Shanahan says he's not certain Donovan McNabb will be available for the Washington Redskins' season opener against the Dallas Cowboys.

"I really don't know for sure," Shanahan said Sunday. "That's why it's day by day. We'll see how it goes."

McNabb hasn't practiced since spraining his left ankle in the second preseason game against Baltimore. He sat out Friday's game against the New York Jets and watched Sunday's practice with a black sleeve on his left leg.

Shanahan said the leg is too sore for McNabb to play Thursday against the Arizona Cardinals, but McNabb likely wouldn't have played in that game anyway because the coach prefers to rest his starters and some of his top backups in the final exhibition to avoid injuries. No. 2 quarterback Rex Grossman said he won't play this week either, leaving John Beck and Richard Bartel to take the snaps against the Cardinals.

The news from Shanahan was more positive concerning running back Clinton Portis, who sprained his right ankle against the Jets.

"I don't think it's too serious. It's not a big setback," Shanahan said. "I would anticipate him being able to practice in a couple of days."

Fullback Mike Sellers, who missed the Jets game, remains day to day with a sprained left knee. Backup linebacker Perry Riley sprained his right ankle against New York and was wearing a walking boot Sunday.
