Euro 2012 qual. - Earnshaw out of England clash
The 29-year-old suffered the injury during Nottingham Forest`s goalless npower Championship draw against Doncaster last weekend.
Although the problem is not as bad as initially feared, scans have revealed the damage will sideline Earnshaw for around a month, ruling him out of the clash at Cardiff`s Millennium Stadium on March 26. "Robert has a grade one hamstring injury, which is good news for us," said Forest boss Billy Davies.
He added: "We are probably looking at him being out for three or four weeks. Anything above that would have been a disaster for us."
