Harry Arter has not been included in the Republic of Ireland squad for the Nations League clash with Wales amid reports he has pulled out following a spat with assistant manager Roy Keane.

The midfielder, who played 90 minutes for Cardiff on loan from Bournemouth in their 3-2 Premier League defeat by Arsenal on Sunday, was included in the initial party for Thursday night’s game in Cardiff and the friendly trip to Poland which follows it.

However, his name was conspicuous by its absence when manager Martin O’Neill announced the final 26-man party on Monday.

O’Neill confirmed last month that there had been a difference of opinion between Keane and Arter and striker Jonathan Walters before the June friendly against the United States.

Walters has been included in the squad, although had not joined up in time for Monday morning’s first training session in Abbotstown after playing 90 minutes for Ipswich in Sunday’s 1-1 derby draw with Norwich.

Southampton striker Shane Long has missed out with a foot injury suffered in his club’s 2-0 Premier League win at Crystal Palace on Saturday, joining James McCarthy and Robbie Brady on the casualty list.

Shane Duffy and David Meyler sat out the first training session as a precaution with groin and knee problems respectively, but both are expected to be fit for the Wales game.

Uncapped Kristiansund BK keeper Sean McDermott and Preston striker Callum Robinson remain in the squad.
