West Bromwich Albion captain Dara O'Shea is to miss the Championship run-in with a knee injury, while fellow Irishman Jayson Molumby could also miss most of the remainder of the season.
O'Shea suffered his injury 12 minutes from the end of Monday's 1-0 friendly international defeat by France.
Molumby then limped off eight minutes later with a groin problem.
Albion boss Carlos Corberan said O'Shea will be out for the rest of the season and expects Molumby to miss four weeks.
With the regular Championship season scheduled to finish on 7 May, Molumby's best chance of returning to action is if Albion make the play-offs.
