Alan Solomons has been forced to make a number of changes to his side to play Neath tonight at Ravenhill due to Jonathan Bell's niggling ankle injury and a bout of the flu which has affected both Bell and Robbie Kempson.
Shane Stewart will replace Bell in the centre and Jan Cunningham has been brought into the squad to take Stewart's spot on the bench.
Simon Best will replace Robbie Kempson and Clem Boyd will now feature on the bench.

Replacements: C Boyd, P Shields, P Johns, N Best, K Campbell, J Cunningham, S Young.
