Northern Ireland boss Michael O'Neill is sweating on a fitness update regarding Liam Boyce today with the striker a major doubt for the double header against San Marino and the Czech Republic at the start of September.
The former Cliftonville hero suffered a bad knee injury while playing for Burton Albion on Saturday and now looks set for a spell on the sidelines.
It's a cruel blow for the 26-year-old who moved from Ross County to The Brewers last month and scored Northern Ireland's winner in a 1-0 friendy victory over New Zealand in June.
Boyce was stretchered off in the first half of the 1-0 friendly defeat at Shrewsbury Town.
Burton boss Nigel Clough said: "We'll know a bit more on Monday after a scan. We are not sure yet. It was innocuous. He just put his foot down and just felt something in his knee."
Boyce's former Reds team-mate Joe Gormley netted a hat-trick for Cliftonville in a 6-0 win at Shelbourne in a pre-season friendly yesterday.
