Jimmy Keinhorst cup-tied for Widnes; Leeds without Brad Singleton

Jimmy Keinhorst will be unable to play for Widnes on Friday due to being cup-tied and Leeds will be without Brad Singleton.

Brian McDermott has made just one change to his Leeds side that lost to Warrington Wolves last week. Mikolaj Oledzki replaces Brad Singleton, who broke a bone in his hand last week. Jack Walker is back in contention after featuring for the Under-19s last weekend.

Widnes coach Denis Betts has made three changes to his team that lost at Huddersfield Giants last time out. Ted Chapelhow, Ed Chamberlain and Stefan Marsh come in for Keinhorst, Danny Craven and Patrick Ah Van.
