Speaking to Sky Sports, Tindall said: "He was taken to hospital on Friday evening, so everybody wishes him the best and I'm sure he'll be back with us again soon."
Tindall was also asked if Howe had had any input on team selection for the United clash and added: "I think when you've been ill all week it's very difficult to have the kind of input that I'm sure he'd normally have, but the way we work we know the expectations, we've got a fantastic group of players, and they know the demands that the manager and everybody else will put on them, so it;'s important that they go out and deliver the performance that the manager will be proud of."
