Leeds boss Brian McDermott has named his strongest possible side, with recent Golden Boot winner and England Captain Kevin Sinfield, as well as new signings Joe Vickey and Joel Moon all included in his starting line-up.
The referee is Oldham's Robert Hicks.
Bulls Squad is:
Foster, Kear, Blythe, Lulia, Platt, Kearney, Sammut, Scruton, Diskin, Manuokafoa, Olbison, Whitehead, Walker, Sidlow, O'Brien, Murphy, Addy, Donaldson
The Bulls will also play in their new Away Kit for the first time.
With the early pre-season friendly not only marking Cummins' first game against Super League opposition and a return to the club where he accomplished a successful career as a player and assistant coach, but also marking the well-deserved testimonial of Leeds' Danny McGuire, now in his 13th season with the Rhinos.
Cummins has been left in no doubt that his Bulls side will be made to work harder against their arch enemies than they were in last Sunday's first run-out of the year against Dewsbury.
The convincing 48-6 Tetley's Stadium triumph over the Dewsbury Rams.
Cummins said: "With no disrespect to Dewsbury, we know as a team it will be a harder game than last week.
"We played really well against the Rams and the team enjoyed themselves, with the good coaching, hard work and steps we've put in training paying off on the field, but this week it will be totally different."
While the Bulls co-captain Heath L'Estrange echoed his coaches comments, saying: "The win over Dewsbury was really good and while you could say it's been the best pre-season fixture I've been involved in with the club. We as a side aren't getting carried away with it.
"Despite this being a friendly, I have never played in a Bradford v Leeds game that hasn't been physical, and I am sure that this one will be no different."
"The game on Sunday should be a bit of a measuring stick for us and an ideal opportunity to see exactly where we are in relation to our preparations for the coming season. Not to mention it being a great cause for Danny McGuire, a true great of the modern game."
