Team manager Simon Hicks has made just two changes to the JCT 600 Bradford League side for next Sunday's White Rose Trophy first round tie against the Huddersfield Central League at Thurstonland.
Rennison, who joined East Bierley from Doncaster Town this season, takes the place of Manningham Mills batsman Amar Rashid who has withdrawn from the side.
Keighley's talented all-rounder Max Davidson, Jonathan Rudge (Spen Victoria) and Morley off spinner Tom Smith - who were all called up as late replacements for the original match which had to be called off due to rain on May 13 - retain their places and will make their debuts
With Kasir Maroof and Fahid Rehman needed for Bradford's Joe Lumb Competition clash against Heavy Woollen at Undercliffe on the same day, Hicks has brought Rennison) and Tom Pringle (Cleckheaton) .
But team-manager Hicks is aware that he could lose both players and skipper Mark Robertshaw to the Leeds/Bradford Universities Centre of Cricket Excellence. All three could be called up for a match next Sunday.
He said: "I have decided to select them in the hope that they will be able to play because they are key players. However, if they do have to pull out I will go and find replacements. I feel it is better to do that than leave Robertshaw, Rennison and Pringle out, only to find at a later date that they are available.
