Chance for youngsters to impress.
It's the first of two matches for the U's on Tuesday, ahead of the first team fixture against Sheffield United at the Weston Homes Community Stadium.
The match against the Bees, which kicks off at 1pm, will give the young players a chance to impress boss Tony Humes.
So far, the U's U21s have won one, drawn one and lost one and, with a win in their last game at Crewe, they'll be hoping to build on that this afternoon.
U's: Bransgrove, Carroll, Vincent-Young, O'Donoghue, Brampton, Roast, Lokko, Drey Wright, Lapslie, Curtis, Hubble, Harrison, Issa, Sembie-Ferris, Smith, Nwachuku, Triallist
