Arsenal midfielder Aaron Ramsey was forced to withdraw from Wales's 2-1 win over Andorra on Tuesday night through injury.
Ramsey was hurt after appearing to slip on the 3G surface, and was replaced by Manchester City youngster Emyr Huws in stoppage time.
It is unclear what exactly the problem is, but the 23-year-old is likely to be assessed by Arsenal's medical team when he returns to London.
Gareth Bale, who scored both goals for Chris Coleman's side, slammed the condition of the artificial surface after the game.
