Martin Hinshelwood has appealed to Albion fans to arrive early at Leyton Orient on Saturday to roar on the youth team.
The kids kick-off against Orient at the Lea Valley Leisure Centre at 11am, before Micky Adams' high flyers play a crucial Division Three fixture at nearby Brisbane Road four hours later.
The under-19s are attempting to retain their Youth Alliance play-off title.
Hinshelwood, the director of youth, said: "It will be a tough game for them. They went there earlier in the season and got a 2-1 win but it was close.
"It would be great to see a few supporters there to help encourage them before they go to see the first team."
Albion secured their play-off spot despite being unable to fulfill their fixtures by the February 24 deadline due to postponements.
Hinshelwood said: "We managed 40 points from 20 games, which was two short, and that got us second and into the top play-off group again."
They clinched their place with a 4-0 victory over Portsmouth, first-year youth Daniel Beck hitting a hat-trick and defender Kevin Hemsley chipping in with the other goal.
