Martin O'Neill has confirmed the full-back picked up the injury against Wales, and both club and country are waiting to learn the severity
Everton are set to be without Seamus Coleman for the visit of West Ham on Sunday after the full-back sustained a foot injury on international duty with the Republic of Ireland.
Coleman, who is not long returned from ten months out following a horrific leg-break in March 2017, picked up a stress fracture during his country’s 4-1 defeat by Wales in Cardiff on Thursday, and Ireland boss Martin O’Neill expressed worry about his captain ahead of the resumption of the Nations League next month.
