Defender comes on as half-time substitute
Oscar Threlkeld came off the bench to make his Plymouth Argyle league debut away at Stevenage on Saturday.
The defender replaced Kelvin Mellor at half-time as the Pilgrims found themselves 2-0 down thanks to first half strikes from Connor Ogilvie and Chris Whelpdale.
Craig Tanner halved the deficit for Plymouth shortly before the hour-mark, but it proved to be just a consolation come the final whistle as Derik Adams' side slipped to third place in League Two.
