Toon midfielder Sean Longstaff has been ruled out with an ankle injury.
“Unfortunately, Sean Longstaff turned an ankle yesterday in training. He won't make tomorrow," Steve Bruce said.
“He tried to block a cross and unfortunately twisted his ankle and we won't know how severe that is until the next couple of days. That's a bit of a blow to us.
“It's one of those freak ones which unfortunately happen. We were disappointed for him that we've lost a player to a freak accident. That's what happens in football unfortunately."
However, Bruce had better news regarding summer arrival Andy Carroll.
“[Carroll has] made big progress this week. He's delighted with how it has gone so far. It's good news for us," said the manager.
“I think for everybody to see him joining in with training was good for him, good for the group of course and we need now some positive news from his specialist.
“He's doing a session as we speak now. We hope all of that is good news. He's certainly comfortable with it and he's close.
“It's always very difficult to put timescale on someone like Andy, he's fit when he's fit. He's joined in, he's worked extremely hard, there's a smile across his face this morning where he's comfortable which is good.
“When you've got an ankle like he's got, it's always the reaction to the work he's put in. At the moment it's all very good."
