Reds full-backs Marciano Bruma and Bobby Hassell will miss this weekend's friendly double header with Buxton and Rotherham.
Reds Boss Simon Davey will send two separate teams to the Silverlands, Buxton (Friday 27th July 7:45pm) and Millmoor Rotherham (Saturday 30th July) but Bruma and Hassell will play no part.
Hassell has been missing for several days after suffering a knee injury in training whilst Bruma suffered a broken hand this week after a training ground collision with Dominik Werling.
Davey told www.barnsleyfc.co.uk:
(on Bruma)
"We are still waiting to find out just what the situation is with Marciano. He had a plate put into his hand on Thursday and will go back to the specialist on Monday to see whether he can play in a plaster cast.
"We will know more then"
(On Hassell)
"We will have to wait and see just how long Bobby will be out for although he did some work yesterday. He is not training with the first team at the moment".
