Leeds United manager Neil Warnock does not expect Aidan White to play again this season after suffering an ankle injury in the defeat to Watford on Saturday. White was a doubt going into the game at the weekend after suffering an ankle injury at Millwall the previous weekend and he lasted just 45 minutes of the game against Watford after suffering a further knock.Speaking in the Yorkshire Evening Post, Warnock said, "It`s not too serious and there`s no break in it, that`s the good thing. But I`d be very surprised if he plays again this season. It`s a shame because he`s done well."The youngster who has come through the Leeds United academy is out of contract in the summer and is yet to agree a new deal with the club.He has been a regular in the Leeds side this season making 39 appearances and he has also broken onto the international scene having played in all 5 Republic of Ireland under 21 games this season.
