Cardiff City may bring some first team players to Edgar Street on Sunday.
The game is being advertised as Hereford V Cardiff City U21's but comments by Steve Morrison suggests he wants some first team players in their squad.
"We've got Swindon, and there's a game against Hereford on the Sunday as well. We then get a nice week leading into Norwich, where it all starts to get real.
"I'm really happy. We've got competition across the board, and the lads have got to push each other. The competition speaks for itself - you look over your shoulder, you've got somebody who wants your shirt."
This afternoon Cardiff's Under 21's won their friendly against Bromley 10-1.
Scorers were Caleb Hughes, Tom Davies, Morgan Wigley, Siya Ligendza and a brace apiece for Joel Colwill and James Crole plus one each for two of the trialists.
Cardiff City u21s XI : Luthra; McNamara, Trialist, Benjamin, Davies; Trialist, Trialist, Trialist; Jefferies, Ligendza, Hughes.
Subs : Semenyo, Turner, Jones, Clay, Ashford, Keeping, Kenniford, Wigley, J. Colwill, Crole.
