The PFA Young Player of the Year limped out of Sunday’s 2-0 win against Fulham and was ruled out of this summer’s tournament less than 24 hours before Hodgson was due to announce his 23-man squad.
Walker tweeted: "Gutted to miss out but going with a broken toe would've been no good to anyone...I know the boys will go all the way!"

However, Walker’s omission failed to open the door for Manchester City’s Micah Richards, who was surprisingly overlooked by the former Baggies boss. Hodgson instead opted for Liverpool’s Glen Johnson and Manchester United youngster Phil Jones.
The England boss told reporters at Wembley on Wednesday: "It was difficult. In Phil Jones we have a player who has done well at right-back. It was one of Jones or Richards."
