Development Squad team-mates George Marsh and Jack Roles faced each other briefly as Leyton Orient and Cambridge United went toe-to-toe in League Two on Saturday.
George started in central midfield while Jack came off the bench to great effect in the second half, scoring as The Us hauled themselves back into the game having trailed 3-0 at half-time. However, it wasn't quite enough for Colin Calderwood's men as Orient ran out 3-2 winners.
The pair were back in their respective starting line-ups on Boxing Day. George played at right-back as The Os lost 3-1 against Colchester United while Jack and Cambridge had one to forget, 3-0 down at half-time in a 4-0 loss at leaders Swindon.
George, 21, has 16 appearances this term while Jack, 20, has four goals in his 15 appearances.
Elsewhere, Luke Amos continues to feature regularly for QPR. The midfielder has played in Rangers' last nine games in the Championship and started again at Reading on Boxing Day - where his team were beaten by John Swift's fine strike in the second half. Luke scored twice in a recent loss at Barnsley and has 16 appearances under his belt, 15 in the league.
Meanwhile, Jack Clarke (Leeds United), Cameron Carter-Vickers (Stoke City) and Kazaiah Sterling (Doncaster Rovers) have been recalled from their respective loan spells and will return to the Club on 2 January.
