YORK City Knights have been drawn at fellow Betfred Championship outfit London Broncos in the fourth round of the Coral Challenge Cup.

The tie is scheduled to be played on weekend of February 22 and 23.

Relegated from Super League last season, Broncos are one of four teams in the second tier to have a 100 per cent winning record from two games thus far, having beaten Bradford Bulls and Whitehaven.

It is one of five all-Championship ties ahead of the fifth round, when the bottom four sides in Super League join the competition.

York Acorn, meanwhile, will face a home tie against British Army should they progress past Rochdale Hornets.

Josh Mortimer's side was due to visit the League One outfit on Sunday but - like the Knights' league game with Bulls - fell foul of the weather.

The rearranged third round fixture was initially pencilled in to be played this Sunday.

The Challenge Cup fourth round draw in full: Rochdale Hornets or York Acorn v British Army; Whitehaven v Dewsbury Rams; North Wales Crusaders v Hunslet; Sheffield Eagles v Halifax; Workington Town or West Bowling v Doncaster; Bradford Bulls v Underbank Rangers; Featherstone Rovers v Barrow Raiders or London Skolars; London Broncos v York City Knights; Swinton Lions v Leigh Miners Rangers; Leigh Centurions v Batley Bulldogs; Siddal v Keighley Cougars or Newcastle Thunder; Widnes Vikings v Oldham.
