Allardyce revealed the striker will be playing a part for the Development Squad later today when they travel to AFC Telford's ground to play Wolverhampton Wanderers.
He told whufc.com: "Carlton's had one game, we started pre-season training on July 1 and spent seven-and-a-half weeks building up to Cardiff, Carlton's been training with us for three weeks and played one game behind closed doors.
"In pre-season terms he's still four weeks off but we have to bring that forward as quickly as we possibly can. He'll be playing in the Under-21s on Monday to get another game.
