West Ham United defender Joey O'Brien has been named in a provisional 29-man squad for the Republic of Ireland's FIFA World Cup Qualifiers against Sweden and Austria next month.

Giovanni Trapattoni's side are set to play Sweden in Dublin on Friday 6 September and Austria in Vienna on Tuesday 10 September.

O'Brien, 27, has been capped five times by his country at senior level, with his last international appearance coming in a 2012 friendly against Oman.

Ireland currently sit fourth in their qualification group, five points off leaders Germany, but level with second placed Austria and Sweden in third.
