It was a very proud moment for both of them. Of course Thomas senior has got well used to tutoring 'junior' as they are both gainfully employed at Dalriada School where 'senior' is the Head.
Gordy McCandless, the Ballymoney thirds captain, was delighted with the new pairing.
"The young cub played at out-half and had an outstanding senior debut. Unfortunately we had the wrong result (31-10) on the day," he said.
"I was surprised how considerate of old age young Thomas was - he was very careful to slow right down at times to let the old fella catch up."
Rumour has it also that at different times Thomas jnr was heard to call out, 'Pass Dad!' and 'Your man Mr. Skelton!', as well as 'Well done Headmaster!'
"What I do know is that it was a memorable day for the players and our club. in all three new, young players started with us and this can only be good for the future," McCandless added.
