Carlisle United winger Lewis Bell was quickly into action in his first game for loan club Gretna 2008.
Bell was named on the bench for the Lowland League clash with Celtic B.
But the 19-year-old was summoned by manager Stephen Hatfield after just 26 minutes.
Russell Currie, who had given Gretna a second-minute lead from the penalty spot, had to go off injured.
That saw a Raydale Park debut for Bell on the day his half-season loan move had been confirmed.
But the Blues teenager's first outing came in a losing cause as Celtic B fought back.
They levelled on 38 minutes when home defender Kieran Moyles bundled a cross into his own net.
And the Glasgow visitors took charge after the break with goals from Bruno Davidson, Tsoanelo Letsosa and Matthew Anderson sealing a 4-1 win.
Bell's next chance to impress could come next Saturday when Gretna take on Cambuslang Rangers in the South Challenge Cup at Raydale Park.
Sam Fishburn, meanwhile, was a second-half substitute as Blyth Spartans went down to a 2-0 defeat at King's Lynn Town in National League North.
The young Blues centre-forward was sent on by interim managers Gary Neasham and Ian Aitken in the 65th minute.
Fishburn was part of a double change with ex-Blues Josh Gillies also coming on at a time the north-east outfit were two goals behind.
He almost set up a goal for JJ O'Donnell with nine minutes to go but the home defence denied Blyth.
Fishburn, 18, then saw a shot blocked in hte box in added time as Blyth - who parted company with boss Terry Mitchell last week - were beaten. They go to Chorley tomorrow in league action.
Max Kilsby got a late sub outing as Peter Murphy's Annan Athletic fell to a heavy defeat.
First-year United pro defender Kilsby, 18, came on with ten minutes to go at Dumbarton.
Annan were 3-0 down and went on to concede another late on as they lost 4-0 in Scottish League Two.
They will hope to bounce back at home to Stirling Albion next weekend.
