Defender misses out after red card.
The U's also have Freddie Sears available after he missed Wednesday's match with a dead leg.
Magnus Okuonghae is likely to step into the team, having started the Boxing Day game on the bench.
Josh saw red early on in the Boxing Day reverse to Brentford and will serve a one game ban. He will be with the U's in the longer term, though, having penned a permanent deal on Friday. The U's will be without defender Josh Thompson on Saturday as they aim to finish 2012 on a high.
