Blackburn Rovers have been dealt a frustrating injury blow, with news emerging that defender Ryan Nyambe was forced to withdraw from the Namibia squad for their recent match against Mali. 

The Lancashire Telegraph reported that Nyambe was named in the starting XI in their African Cup of Nations qualifier, but didn't feature at all during the match, which has raised concerns over a potential injury worry.

Nyambe has made nine appearances so far this season for Blackburn in all competitions, and will be hoping that his injury doesn't keep him out of action for too long.

Rovers are sat 12th in the second-tier standings so far this term, and will be hoping they can improve on last seasons 11th-place finish under Mowbray's management.

Nyambe will return to Blackburn from international duty this week, and it is hoped that Mowbray will be able to provide supporters with an update on his injury picked up in the warm-up for Namibia.

Blackburn are set to return to action this weekend when they take on Luton Town at Kenilworth Road, in what is likely to be a tough test against the Hatters.

Nathan Jones' men are currently sat tenth in the Championship table after their opening 11 matches of this year's campaign, and will fancy their chances of picking up three points against Rovers.

The Verdict: 

This will be a real worry for the Ewood Park faithful.

Nyambe has played his part for Blackburn Rovers in the last couple of seasons, and is a player that would likely be a regular starter in Tony Mowbray's side if he was deemed 100% fit.

But it seems as though that isn't the case at this moment in time, and the Lancashire-based side will be hoping that he isn't ruled out for too long with this injury worry.

Mowbray will be keen to have a fully-fit squad at the earliest of opportunities this term, as Blackburn look to make a serious push for a top-six finish in the Championship.
