Blues will travel to the Capital to take on Ian Hollaway's Coca Cola Championship side at Loftus Road in a testimonial game for Gallen on Saturday, 30th July (kick-off 3pm).
Blues have also pencilled-in a friendly game against Derby County at Pride Park for Saturday, 23rd July although this game is dependent on which league the Rams are playing in next season.
George Burley's side could well be a Premiership side at the end of this season as they are currently occupying one of the four play-off places in the Coca-Cola Championship table and if they do manage to gain promotion to the top-flight then this friendly will NOT take place.
