Tony Mowbray has confirmed that injured pair Harrison Reed and Craig Conway won't be part of the squad for the trip to Queens Park Rangers on Good Friday.
Rovers will head to the capital in fine form following back-to-back victories over Derby County and then Nottingham Forest last week.
Both Reed and Conway started that win against Derby, but missed out on beating Forest at The City Ground due to injury.
And Mowbray had admitted that those issues will keep both players sidelined for Friday's trip south.
“Harrison Reed won’t be available and is getting a check at Southampton at the moment to see how many weeks his injury will keep him out," the boss told iFollow Rovers ahead of the game at Loftus Road.
“It’s just above his left ankle and into his calf, it was an innocuous one in training and we think he’s strained something.
“Southampton will assess things and see where he is, but hopefully it’ll only be a case of him being out for a week.
“He’s a quality footballer, Reedy, and will be a miss, especially after what was for me his best performance of the season in the recent win against Derby at Ewood Park.
“So he won’t be available, but Craig Conway is hoping to train tomorrow in a bid to be ready for Monday against Bolton, but won’t train tomorrow and then head down with us to QPR," he added.
“Apart from that everybody is fit and raring to go."
