BRISBANE has delisted hard-at-it agitator Nick Robertson as it refines its developing list for a strong flag tilt in 2020.

The 24-year-old developed into an effective run-with player with a knack of getting under the skin of some of the best players in the competition, but as young talent has developed around him Robertson has found it increasingly difficult to hold a senior berth.

After playing 42 of a possible 44 games across 2017-18, Robertson managed just five senior appearances with the Lions this year as they headed towards a second-placed finish to the home and away season.

"Robbo has always given 100% at everything he has done; training, preparation, the way he plays," Brisbane's general manager of football David Noble said.

"I am hopeful another club would provide him with another opportunity as a delisted free agent.

"We thank him for his time at the Lions. It's always hard saying goodbye to good people."

Robertson was drafted in 2013 with the 34th overall selection at the NAB AFL Draft, and managed 73 games in his six seasons at the Gabba.
