England coach Roy Hodgson has Liverpool defender Jon Flanagan on his World Cup radar.
The People says Kyle Walker has been receiving painkilling injections for a pelvic problem and the England manager is not prepared to take the Tottenham right-back to Brazil if the issue is not totally resolved.
The injury has led to Hodgson seriously monitoring other options and Liverpool full-back Flanagan has leapt up the Three Lions' pecking order.
He was not even picked for the last England Under-21s squad but, after becoming such an impressive part of the Reds' title drive, he has given himself a real chance of being included in the 23-man squad for Brazil.
