Reading striker Kevin Doyle is set to be out of action for up to a month with a calf injury.

The Republic of Ireland international sustained the problem in the first leg of the play-off semi-final against Burnley and is now a doubt for his country`s clash with Bulgaria on June 6.

However, Royals physio Jon Fearn is confident Doyle will be fit for pre-season and told the club's official website: "Kevin has damaged muscle in his calf but the scans show no damage to the Achilles tendon. It`s difficult to assess how long he`ll be out, but it should be no more than four weeks."
