The German has returned to his parent-club Brighton & Hove Albion to undergo a scan on this particular issue which has forced him to miss five league games.
Signed on a season-long loan deal from the Seagulls last year, Khadra has managed to illustrate some real signs of promise in the Championship this season.
Blackburn managed to secure a crucial victory in the absence of Khadra earlier this week as they proved to be too strong for Preston North End at Deepdale.
Goals from Sam Gallagher, John Buckley, Darragh Lenihan and Lewis Travis sealed all three points for Mowbray’s side.
Now within striking distance of Sheffield United in the league standings, Blackburn will be looking to stay in contention for a place in the play-offs this weekend by picking up a positive result in their meeting with AFC Bournemouth.
Ahead of this game, Mowbray has shared an update on Khadra.
Speaking in his pre-match press conference (as cited by Blackburn’s official Twitter account) about Khadra, the Rovers boss said: “Reda’s in Brighton, I think we should forget about Reda Khadra for the next couple of games.

“If the season’s prolonged then maybe he might have a chance on the back of that.”

This is unquestionably a blow for Blackburn as they would have been hoping to call upon Khadra’s services for their clashes with Bournemouth and Birmingham City.
However, unless Rovers are able to claim the final play-off spot ahead of the Blades and Middlesbrough, the attacker will not feature for them again as his current loan deal is set to expire next month.
Mowbray will be hoping that the likes of Buckley and Ben Brereton Diaz will be firing on all cylinders this weekend.
Buckley provided his ninth direct goal contribution of the campaign against Preston on Monday while Brereton Diaz has managed to find the back of the net on 21 occasions in 35 Championship appearances.
