Manchester United striker Michael Owen has suffered a fresh injury blow.
Owen was expected to start Tuesday's Carling Cup tie against Wolves after recovering from a recent groin complaint.
However, the 30-year-old was a late absentee from the team and has confirmed he has now picked up a fresh muscle problem.
"I've trained for a week and had a setback with another muscle injury," said Owen.
"I've got some damage in my hamstring and will be out for the next few weeks unfortunately."
