Blades boss Kevin Blackwell confirms that there is a definite absentee for tonight's showdown at Deepdale, but wants to keep it a secret. We already know that Gary Naysmith, Ugo Ehiogu and Derek Geary are out for the season, although Ehiogu has been participating in training recently.
The Gaffer also said that another one of his players is rated 50/50. Gary Speed could be back in contention after recovering from a groin injury.
Meanwhile, Lilywhites boss Alan Irvine has Ross Wallace available for selection again. The Scotsman played a big part in United being able to contest for second spot on the final day, when him and his fellow team-mates denied Birmingham promotion to the Premier League with a game to spare. Wallace took his shirt off in delight which saw him receive his second yellow of the game, when his thunderbolt free-kick smashed in off the post with just minutes remaining.
