Guess Who Is 'Doubtful' For Man Utd Match?
The Magpies captain has not featured in any of the club's pre-season fixtures because of a calf problem ... and mumps.
Owen has returned to training but the 28-year-old is not ready.
Keegan: "Michael is back in training but I think to be honest Manchester United will come a bit early.
"It's no good trying to kid people. He just need a week in with the group doing all the things he needs to do and we're not going into that into him now so I think it's very, very doubtful.
"It would be crazy on our part to try and short cut it because it's Michael Owen. We treat him the same any player."
