The HSR Law Community Vase, organised by Doncaster Businesses for the Community (DB4C), starts at 1pm at the club’s Bennetthorpe ground.
Gates will open at noon before the Business All Stars battle it out against the Commercial Legends.
DB4C trustee Richard Clarke said: “We are delighted to support two wonderful local charities with the proceeds from the day going to The Children’s Sleep Charity and Riding for the Disabled at Rossington Hall.”
DB4C trustee Martin Wilmott added: “The event will be great for families with a stir fry noodle bar, Prosecco van, bouncy castle, cupcake stall and children’s entertainment.”
Entry is £2.50 for adults, £5 per family and free for children under 16.
Last year the event raised more than £5,000 for the community.
