Everton captain Seamus Captain is out of Republic of Ireland's World Cup qualifier against Serbia on Tuesday after picking up an injury against Azerbaijan at the weekend.

The Lowdown: Coleman in action

The £4.5m-valued right-back (Transfermarkt) started for his country against Azerbaijan in Dublin on what was a bad day at the office for Stephen Kenny's side.

Ireland could only manage a 1-1 draw courtesy of a late Shane Duffy equaliser, meaning that Kenny is yet to win any of his competitive outings in charge of the country.

The Latest: Coleman injured

Both he and Everton were handed further bad news following Saturday's encounter, as per Irish media outlet RTE.

Coleman picked up an injury in the game and he will now miss the Serbia fixture. While the report did not specify the nature or length of the setback, the 32-year-old may now be a doubt for the Toffees' next match against Burnley in seven days' time.

The Verdict: Blow for Benitez

Coleman is a crucial member of Benitez's squad and a true Everton stalwart, with 353 club appearances. His importance is not only because of his ability and experience - his former manager Carlo Ancelotti compared his influence as skipper to that of Paolo Maldini, John Terry and Sergio Ramos, all of whom are Champions League-winning defenders who worked under the Italian - but because of the lack of right-back options available to Benitez.

Jonjoe Kenny is the only natural alternative to Coleman in the squad, and perhaps that explains why the Merseyside outfit were looking to bring in Serge Aurier, who is a free agent after leaving Tottenham (via The Daily Express). Hopefully, Coleman's issue is not serious and he can return to action soon, but Benitez and Toffees fans face a nervy week to see how severe his injury proves to be.

In other news, Everton wanted to sign this ace during the transfer window.
