Ireland manager Martin O’Neill confirmed what was apparent from the match replay: the Everton man has a broken ankle.
“It’s a bad break. He’s a fantastic player and character. It’s a major blow for the lad, his club and us.
“Apparently it wasn’t the best challenge in the world – I haven’t seen it. He’s gone to hospital. I saw his reaction immediately and it didn’t look good. He was holding is leg up and it didn’t look good.
This is not only awful for the player, but causes stress as Everton mounts its assault on the Top Six. The right back has also manned right mid for Ronald Koeman this season, and has four goals and four assists in 26 Premier League matches.
