Brisbane prop Adam Blair has pleaded guilty to trippingand received a $1,100 fine.

Blair was the only player charged by the NRL match review committee from the first weekend of the finals, over his trip on Roosters hooker Jake Friend in the eighth minute of Friday night's loss in Sydney.

The Broncos and Kiwis captain will be free to play in Brisbane's semi-final against the Penrith Panthers at Suncorp Stadium this Friday night.
