The money raised will go towards paying the Merthyr players wages and other costs as the Martyrs look to make a dent in their £300,000 debt.
The Cardiff City line up will include former Czech Republic Under-21 striker Daniel Kolar. The 23 year old has played for Sparta Prague and currently FC Viktoria Plzen. He will have a chance to show Dave Jones what he can do.
Players like Darren Purse, Riccy Scimeca and Quincy Owusu-Abeyie are all set for a run out as Jones will look get match action for those not playing first team football week in week out.
The match kicks off at 7:45pm and entry costs £5 for adults and £2 for U16's. All proceeds to Merthyr FC.
