Port Vale's Marc Bridge-Wilkinson will not be risked when Wycombe visit the Second Division leaders on Saturday.
Horton's Port Vale are the early Second Division leaders
The former Derby player has a knee injury, but there is better news for fellow midfielder Liam Burns, recovering from an ankle problem, and another knee injury victim - Michael Cummins.
"Bridgey is close to full-time training, but he won't be ready for Saturday," boss Brian Horton explained.
"Liam is back in training, but Michael hasn't trained all week so we are going to have to see how he is nearer the game.
"It has done Michael Walsh good to have a game and a full week's training, but we must keep monitoring what he does," he told Vale's website.
