Sunderland suffer Granit Xhaka injury blow against Chelsea as Regis Le Bris forced into early change

Sunderland were dealt a major injury concern just a few minutes into their Premier League clash with Chelsea, as Granit Xhaka was forced off with a suspected calf problem.

The former Arsenal man unsurprisingly started the Stadium of Light encounter against the Blues, who were interested in signing him during the summer transfer window.

Xhaka ultimately snubbed interest from the West London giants to remain with Sunderland, but he did not get the chance to show his former admirers what they are missing out on.

With just a couple of minutes gone on Sunday afternoon, the Switzerland international dropped to the turf and eventually had to hobble off after receiving treatment.

Xhaka - who was replaced by Jules Ahoka - appeared to have sustained a calf problem, although he was able to take his place on the bench shortly after being withdrawn.

Regis Le Bris will be quizzed for an update on Xhaka's injury at full time, but Sunderland will need to send the midfielder for tests to determine the severity of his problem.

However, if Xhaka has suffered a calf injury as expected, the 34-year-old's recuperation period could range from a couple of weeks to a few months depending on the grade of his concern.

A Grade 1 issue - or mild strain - usually takes one to two weeks to heal, meaning that Xhaka could return in time for Sunderland's clash with Aston Villa on November 21 following the international break.

A Grade 2 injury could rule Xhaka out for up to six weeks, though, putting him at risk of missing games against Jagiellonia Bialystok, Tottenham Hotspur, Liverpool, Newcastle United, AC Milan, Nottingham Forest and Crystal Palace between now and Christmas.

Meanwhile, a Grade 3 injury - a complete tear - would likely sideline Xhaka for three months, forcing him to sit out clashes with Manchester United, Chelsea and Liverpool either side of the New Year.
