Brisbane have stunned Hawthorn and given the Hawks' AFL finals aspirations a serious hit with a 33-point win in Launceston.
The Lions attacked the footy harder than the Hawks in the 15.8.98 to 9.11.65 victory on Saturday afternoon - their third in a row.
Young guns Cameron Rayner and Eric Hipwood booted three goals each, including crucial majors at the beginning of the fourth quarter.
In match that ebbed and flowed, the Lions held a 72-64 lead heading into the final term, when they ran rampant.
The Hawks managed only one point in the last quarter, while the Lions booted the last six goals of the match.
The win was made even more impressive in the absence of star Luke Hodge, who was a late withdrawal with a sore calf.
Dayne Beams was one of the best on ground with 33 possessions, seven clearances and two goal assists.
Hawthorn were eighth going into the round but could drop as low as 10th after their second loss in three games.
Tom Mitchell finished with a game-high 43 touches but was kept quiet in the second half after racking up 29 of those by the main break.
Jaeger O'Meara was the top goalkicker for Hawthorn with four but none came in the final quarter when the Hawks needed it the most.
