Irish all rounder Kevin O'Brien has suffered a hamstring injury while playing for Middlesex Seconds, and faces a race against time to be fit for the European Championships and Twenty20 World Cup Qualifiers.

He is likely to be out for between 3-4 weeks, which means he will miss the games against Bangladesh 'A' next week, as well as the ODI's against New Zealand and Scotland in Aberdeen at the start of July.

He was due to captain Ireland 'A' in a 3 game at Trinity starting on Monday. His place will be taken by Andrew Balbirnie, as original 12th man for the game Shane Getkate is returning to the Warwickshire Academy after the Lashings games on Sunday. No replacement captain has been named yet, with Irish coach Phil Simmons waiting until after the games on Sunday to assess form and fitness.

He will also name his squads for the full Irish games against Bangladesh 'A', and the ODI's in Aberdeen on Monday.

William Porterfield and Gary Wilson are required by their counties this weekend, and there are doubts over the availability of both Jeremy Bray and Andrew Britton, who both have Senior games with their clubs scheduled for Sunday.
