Hereford play their last home pre-season friendly on Tuesday evening.
Aston Villa Under 21's are the visitors to Edgar Street and are expected to be much tougher opposition than Swindon last Tuesday.

"It will be very tough for us," said Hereford manager Paul Caddis.
"They've spent a lot of money on even the Under 21's.
"It will be one of those ones when we will be tested.
"If one player is one second out they'll play through you."
The final pre-season game is away at Redditch next Saturday, 3pm kick-off.
