City's top scorer came out of Tuesday's win over Swansea with a dead leg and hasn't been able to train since. However, Tigers boss Peter Taylor says that he's "hopeful he is going to be okay." Jamie Forrester may be recalled if Allsopp is absent, while Stuart Elliott, Jason Price or Stuart Green could also move up front.
Taylor added: "The really positive news is that Alton Thelwell and Marc Joseph trained today so we had 24 players training and that's very encouraging.
Allsopp Injury Worry
"They won't come into my thinking this weekend. I'm hopeful that they are going to play in the reserves against Barnsley the following Wednesday."
That game against Barnsley on the 8th will be the last ever senior game at Boothferry Park, with the reserves moving to Church Road in North Ferriby.
Meanwhile, Greg Strong is returning from his two-month loan spell at Bury. The centre back was ever present for the Shakers, playing in each of their opening 11 games of the season, but was left on the bench as they beat York on Tuesday and manager Andy Preece won't be extending the deal.
