Newcastle striker Michael Owen is out of Saturday's pre-season friendly at Carlisle after picking up a thigh injury in training.
Owen will be rested as a precautionary measure
The 27-year-old is also likely to miss Celtic's visit to Tyneside on Thursday evening, but boss Sam Allardyce expects Owen to return within 10 days.
He said: "Hopefully, it will be no more than 10 days and he should be back.
"It may be a little early for the Celtic match, but we hope he will be fit to face Juventus on the Sunday."
Meanwhile, Newcastle boss Sam Allardyce revealed that he will speak to midfielder Kieron Dyer following speculation that West Ham were going to make an offer the the 28-year-old.
He said: "I suppose I will have to have a chat and a conversation with Kieron to see if he thinks there is anything in it and if there is, we will discuss it privately from there.
"But at the moment, there is no bid from West Ham, so until Alan Curbishley rings me or the chief executive rings (chief operating officer) Russell Cushing, then there would be no discussion.
"It has been rumoured in the papers and sometimes there is no smoke without fire.
"But if there's a bid going to come in, I would probably expect a phone call either today or over the weekend because they have lost one of their new players."
