Robbie Keane out for up to six weeks

Los Angeles Galaxy striker Robbie Keane has revealed that he could be out for up to six weeks following an adductor muscle injury.

The 31-year-old was forced to miss the Republic of Ireland's Euro 2012 qualifier against Armenia on Tuesday and he could now be sidelined for their two-legged playoff against Estonia.

"It's a four-to-six week injury, but I'll have a scan and we'll know more in 10 days. It's a muscle injury not just pain," said Keane. "I would love to play in the Euros and I'll do everything I can - the lads will as well."

The first leg will be played on November 11 or 12, followed by the second on November 15.
