Roy Keane says Jon Walters is almost certain to miss Saturday's game at Plymouth.

The striker limped off in the final minutes of Tuesday's draw with Watford with an ankle strain and has not trained since.

"Jon is very doubtful but we will make a final decision later this morning," Town boss Roy Keane told the Club website.

"He won't train today and when you don't train the day before a match it's always a problem at this level.

"He's probably a few days off being fit and we don't want to risk him, as much as we will miss him because he's one of our leaders."

Connor Wickham definitely misses the game as he's away on international duty with England U17s.
