Wales forward Hal Robson-Kanu is set to be ruled out of Wales’ pre-Euro 2016 friendlies.
The Reading forward was unable to train on Tuesday due to a leg injury, despite linking up with the rest of the squad.
The 26-year-old was injured in the first half of Saturday’s 1-1 draw against Cardiff.
Wales face Northern Ireland on Thursday at the Cardiff City Stadium, before facing Ukraine away, four days later.
Defender Neil Taylor missed Swansea City’s 1-0 win over Aston Villa on Saturday because of a dead leg.
But the 27-year-old is expected to be fit for Thursday’s visit of Northern Ireland.
“He was almost ready on Friday but I preferred to stop him because he is an international player with games coming up,” said Swansea manager Francesco Guidolin.
“He has had a heavy season so I felt it best not to risk him. He will be fit for Wales.”
Reading manager Brian McDermott said Robson-Kanu was also doubtful for their next Championship game at Bolton on 2 April.
Robson-Kanu missed November’s 3-2 friendly defeat by the Netherlands because of an ankle injury.
Forward Gareth Bale has been left out of the squad in a joint decision between the Football Association of Wales and his club Real Madrid.
Wales are also without Aaron Ramsey, James Collins, Andy King, Paul Dummett and David Edwards through injury and illness.
