The game kicks off at 2.30pm and can be watched online before being repeated on the Welsh channel at 11.10pm the same evening.
Sir Gar need a win to stay clear of the ever dangerous Llandovery College who showed just how dangerous their backs can be in a comprehensive victory over Pembrokeshire College last week.
George North's former college ran in nine tries but it was hooker Daf Hughes who was the star as he crashed over for a sublime hat trick in a 59-0 win. This week Llandovery face an away trip to Neath Port Talbot College who were narrow winners over Gower College in last week's televised game.
In the other two games to take place tomorrow, Pembrokeshire College host Coleg Gwent at Neyland RFC while Gower College travel to Bridgend College.
