England boss Roy Hodgson said he was reeling Thursday from the loss of a second key midfielder in the space of a week.
"It's a huge blow for the team, especially coming after the loss of another senior player in Gareth Barry," Hodgson said.
"The fact that the doctor cannot guarantee Frank could take part in any of the group matches means we have to replace him in the central midfield area.
"Apart from it being a huge blow to me and the team, I'm especially disappointed for Frank himself.
"He has been in very good form and was looking forward to the tournament.
"He made a huge contribution towards us qualifying for the Euros so it is cruel to be forced out through injury just before the tournament."
