Razak Boukari is expected to be sidelined for another two weeks after suffering a reaction to the final stages of his return from injury.
The winger had been eased back through the different stages of training after out with a calf injury but struggled at the final stage where needing to use his explosive pace.
“Boukari is out for another two weeks,” confirmed boss Ståle Solbakken.
“He did the whole training session but got pain afterwards.
“He’s seen two specialists and I think he’ll be out for another two weeks.”
The boss has also provided an update on the other injuries currently in the Compton treatment room.
“Slawomir Peszko (knee) is going a little bit quicker than we thought, but we’re talking January 1,” he added.
“Georg Margreitter was back on track with his hip injury but then Bjorn Sigurdarson, who has got power back in his body now and wanted to get into the team, knocked him almost unconscious in training so he’s had a headache now for four or five days!
“Perhaps that’s a blessing to give him four or five days off from the hip.
“I don’t know when Jamie O’Hara will be back.
“He was running outside yesterday again and should have the ball out later this week.
“Steven Mouyokolo is still fighting back, and Stephen Hunt is recovering, going slowly forward in the right direction but it will be a long time.”
