Josh Onomah could be out for at least a month after suffering a new hamstring problem.
The Tottenham loanee returned to action as a second-half substitute at Ipswich on Saturday after being sidelined since picking up a hamstring injury at Middlesbrough on Boxing Day. However, he suffered a hamstring pull in the other leg in the closing minutes at Portman Road and Steve Bruce expects him to be out for at least three to four weeks.
