The Rangers midfielder sustained a medial ligament injury during training at the end of last week and so will be forced to sit-out the match at The Hawthorns on Monday night.
Buzsaky now face's a race against time to be fit in time for the game against Sheffield United this coming Saturday.
"Akos suffered a slight medial ligament strain during shooting practice on Friday," QPR physio Paul Hunter has confirmed.
"It's not a serious injury but he's not in a position to travel to the game.
"We will see how he is over the next couple of days before making a decision regarding his potential inclusion against Sheffield United."
