The striker was called up to Roy Hodgson’s England squad for the recent international friendlies against Spain and France, but played no part in either after failing to recover from groin and hip injuries sustained in the 2-1 win over Watford earlier this month.
Vardy now faces a race against time to be fit for Saturday’s clash at St James’ Park, where he has the chance to equal Ruud van Nistelrooy’s Premier League scoring record.
The 28-year-old has found the back of the net in his last nine successive games, and knows that a single goal against Steve McClaren’s side would etch his name in the history books alongside the Manchester United legend.
Vardy is apparently desperate to make Claudio Ranieri’s side, and it has now been claimed that he is considering taking pain-killing injections after relying on them for a short while under Nigel Pearson last season.
Fortunately for Leicester fans, Vardy’s record would still be intact for the following match against the Red Devils at the end of November if he is unable to face the Magpies.
