Redskins Preseason: Donovan McNabb Sits Out Practice With Ankle Injury

After leaving the Redskins' preseason game against the Ravens early with a sprained ankle, Donovan McNabb emerged from Redskins practice today with a walking foot on his left boot. Via Mike Jones of TBD:

Washington Redskins quarterback Donovan McNabb was wearing a walking boot on his left foot during locker room availability earlier this morning, and just a bit ago during the open portion of the team's practice, the quarterback was an observer.    

McNabb's absence was reportedly merely for "precautionary" reasons, but it's something to watch as the season approaches. 

Mike Sellers, who also injured himself in the preseason game, did not practice either. Malcolm Kelly, who hasn't practiced all of training camp, also sat out.
