Middlesbrough defender Robert Huth will have tests in the next 24 hours to establish the full extent of a foot injury he suffered in training.
Huth signed for Boro on transfer deadline day
The Germany international definitely misses Saturday's game against Wigan.
The centre-back signed for £6m from Chelsea in the summer but missed the start of the season after undergoing an ankle operation.
Huth scored his first goal for Boro, which was also his first Premiership strike, against Tottenham on Tuesday.
