Bruno admits he needs another week to feel in peak condition for Albion.
The Spanish right-back lasted 74 minutes against Hull on Saturday after missing nine of the ten previous matches due to an Achilles injury and a bout of 'flu.
Bruno said: "The Achilles is really good now but two months is a long time to be out and I need a week more before I feel 100 per cent.
"It was really nice to play again and I am especially happy with the three points, because it was really important for us."
Bruno will line up again in the back four with Matt Upson for Blackburn's visit to The Amex tomorrow night after the on-loan former England centre-half made his home debut against Hull.
"He is a good player," Bruno said. "He has a lot of experience and he is a different central defender, because he is left-footed. It is easier for him than, for example, Adam El-Abd or Dunky (Lewis Dunk)."
Captain Gordon Greer (hamstring) is again ruled out of the clash against his first English club, together with midfielder Andrew Crofts (hamstring), while striker Ashley Barnes serves the second game of his three-match ban.
