Enoch Showunmi, Marcus Heikkinen and Kevin Foley are all doubtful after missing the Hull game. Enoch picked up an injury just before the match on Saturday so he lost his place on the bench to Calvin Andrew, who has already spent a month on loan at Grimsby. Fortunately, Calvin didn't appear in Grimsby's 1-0 victory at Derby in the first round, so he will definitely be available tonight unless he gets injured. Luton haven't managed to progress further than the Second Round since the 1998/99 season when we lost to Sunderland in the quarter-finals.
