Donovan McNabb will miss Friday night’s game against the Jets with what team doctors are officially calling a mild cankle sprain.

“Donovan uses his cankles more than most quarterbacks, so this was bound to happen,” said head coach Mike Shanahan. “He’s walking on the treadmill and should be up and wobbling on two healthy cankles in no time.”

The injury is just the latest in a series of setbacks for McNabb, who sat out the last half of an August 13 game against the Bills with sore breasts.
