Burnley have announced that Danny Ings is to visit a specialist in an effort to determine the severity of the knee injury he suffered against Rochdale.
The promising striker picked up the knock during the Clarets' final pre-season friendly on Tuesday.
He was forced off during the second half at Spotland after damaging his left knee.
The 20-year-old has undergone initial medical checks, but the full extent of the problem remains unclear.
Ings has endured wretched luck with injuries since joining Burnley last summer.
Eddie Howe returned to his former employers Bournemouth to snap up the youngster and has been tipping him to make a big impact at Turf Moor.
A cruciate ligament injury laid him low in 2011, though, with surgery required to return him to full fitness.
Ings is now facing up to another spell on the sidelines, with it likely that he will miss the start of the 2012/13 campaign.
"The striker has had an initial scan on the injury which forced him to come off during the second half of the game at Spotland on Tuesday night," read a statement released on the club's official website.
"Ings will now visit a specialist for a further assessment on the injury, which is to his left knee and not the knee which required surgery last August after he suffered cartilage damage in training."
