ADAM Bogdan has emerged as a doubt ahead of tomorrow night’s derby against Blackburn Rovers.

The Hungarian keeper has been carrying a slight groin problem in recent weeks, and the injury is thought to have worsened in Saturday’s 3-2 victory over Barnsley.

Wanderers will wait to see whether treatment enables the 25-year-old to turn out at the Reebok, but Andrew Lonergan has been placed on stand-by, just in case.

The former Leeds United keeper has not yet made a league appearance for the club but has impressed in four outings in the cup competitions.

His last league game came for Leeds against Leicester City last April.
