Luton will be without suspended duo John Mullins and Danny Hylton for their Sky Bet League Two clash with Cambridge.

Mullins was shown his second red card of the season in last weekend's draw with Wycombe and must sit out the next four games.

Hylton, meanwhile, picked up his 10th booking in the same game and is suspended for two matches. Alan Sheehan is available, though, after serving his own ban.

Cameron McGeehan is making good progress in recovering from his broken leg and could be available before the end of the season.

Paul Lewis is still waiting to make his Cambridge debut after being an unused substitute in the last two matches.

Shaun Derry could also hand a debut to defender Scott Wharton, who has signed on loan from Blackburn.

Brad Halliday (knee) failed a late fitness test before the Mansfield game last weekend and has not been in training since.

But Harrison Dunk has recovered from a hamstring injury.
