Stoke City winger Matthew Etherington is facing a fitness race to feature in the FA Cup final on May 14th.
The former Peterborough United, Spurs and West Ham speedster pulled up suddenly in the 3-0 win against Wolves last night, and has instantly become a doubt for the Wembley showpiece against Manchester City.
It would be a cruel blow for the left-sided midfielder, whose form for the Potters have led to calls for an England call-up in recent months.
"It would be a massive disappointment if Matty misses the final," manager Tony Pulis told the official Stoke City website.
"We will know more when he has the scan. We've got seven or eight days to get it right then 10 days to get it as strong as possible."
Etherington scored the opener in the 5-0 semi-final victory against Bolton last Sunday, and currently joins Ricardo Fuller on the treatment table a the Britannia Stadium.
