Titans QB Steve McNair will be wearing a boot on his left foot for at least five days to heal a sprained ankle.

But Coach Jeff Fisher said yesterday that he isn't close to benching McNair for backup Neil O'Donnell.

"He's got to be pretty banged up," Fisher said about benching McNair. "You saw him run around [Thursday night]. He ran for a pretty big first down, he ran around and found Eddie [George] on a scramble. He's not isolated to the pocket now. He still has the ability to move."

McNair also is suffering from turf toe on the same foot that was stepped on last week in a 41-14 loss against the Ravens. He misfired on several passes in the first half Thursday night in a 21-14 victory over the Raiders, and fans chanted for O'Donnell several times as McNair even short-hopped one pass.

Fisher expects McNair to be ready when the Titans practice Wednesday and then will gauge his mobility. Their next game is a week from Sunday against the Falcons.

McNair has not thrown a touchdown pass in six games.

* COX OUT: The Jets placed LB Bryan Cox on injured reserve with a torn abdominal muscle, effectively ending his season. The team said it didn't have any immediate plans to replace the 31-year-old linebacker on the roster.

Cox played in all 12 games this season. He made 45 tackles, intercepted one pass, which he returned for a touchdown, forced two fumbles and recovered one.
