Chris Brunt will undergo a scan today and the result could leave his Euro 2016 dream in tatters.
Brunt and his Northern Ireland manager Michael O'Neill will be holding their breath as the winger has checks carried out on a knee injury he suffered while playing for West Bromwich Albion in their 3-2 win over Crystal Palace in the Premier League on Saturday.
The 31-year-old was carried off just before half-time and there are fears that he may have suffered a cruciate ligament injury.
With just 14 weeks to go until Northern Ireland make their first appearance at a European Championship finals, Brunt would definitely be ruled out if cruciate damage is diagnosed.
West Brom manager Tony Pulis said: "Chris Brunt is going to see a specialist so we will wait until he's done that until we announce what is wrong with him.
"There are all sorts of different opinions so we will wait until the specialist sees him."
