Boro will assess the welfare of striker Chuba Akpom before making a decision on his availability for Saturday's visit of Nottingham Forest.
The summer signing missed the midweek win over Coventry City due to illness and he will be assessed by the club medical staff today before any decisions are made.
“We were all relieved to find out he tested negative for coronavirus,” said boss Neil Warnock. “That was really good news, and he’ll be in today to see the doc.
“He has a very heavy cold so I don’t want him getting too close to the lads. Even if he comes back on the bench it will good news for us.”
The boss will otherwise select from the same squad as Tuesday evening.
“We have one or two little knocks, bit they’re all in good spirits,” said Warnock.
“It’s just game to game at this time for us. We’re going to have to be fortunate not to have injuries because we just haven’t got the cover.”
Grant Hall and Ashley Fletcher remain sidelined through injury.
