Manchester United skipper Wayne Rooney is a doubt for England's Euro 2016 qualifier against Estonia on Friday (9 October) after he picked up a knock during the Red Devils' Premier League loss to Arsenal on Sunday (4 October). The striker missed training on Tuesday afternoon, as the rest of the Three Lions squad prepared for the game at their training base in St George's Park.

"Captain Wayne Rooney, first-time call-up Danny Ings and midfielder Jonjo Shelvey did not train after picking up knocks for their clubs at the weekend," a statement on the Football Association (FA) official site read.

The England medical team will assess the striker's condition through the week before making a decision regarding his participation in the game on Friday. The England international is set to be honoured ahead of the game against Estonia at Wembley after he surpassed Sir Bobby Charlton to become England's leading goal-scorer.

It will be a cause for concern for Louis van Gaal, who is tasked with motivating his players following a disappointing loss at the hands of Arsenal, and will hope to have his captain back for their clash against Everton on 17 October, just after the ongoing international break. Rooney has been struggling for form this season, and has managed just one goal in seven Premier League appearances, but David Beckham has backed the striker to silence critics.

Meanwhile, Roy Hodgson has called up Tottenham duo Kyle Walker and Andros Townsend after Everton star John Stones, who missed the Merseyside Derby on Sunday, withdrew from England duty with an injury.

"The injury to Stones, and the doubts over Rooney, Ings and Shelvey, meant that Hodgson decided to bring in Tottenham Hotspur duo Andros Townsend and Kyle Walker to bolster his numbers," the FA statement added.
