Emerging ruckman Reilly O’Brien will continue to pull on the Crows’ tri-colours after signing a two-year contract extension.

O’Brien, who was originally picked up in the Rookie Draft of 2014 from the Calder Cannons, will remain at West Lakes until at least the end of 2019.

The 21-year-old has impressed during his time at Adelaide earning his AFL debut in Round 20, 2016 against Brisbane where he had 29 hit-outs and kicked a goal.

Crows Head of Football Brett Burton said O’Brien was an important part of the Club’s future.

“We are thrilled to have Reilly re-sign with Adelaide,” Burton said.

“To see him progress initially from the rookie list to earning a senior debut last season is a credit to him and the Club’s coaching staff.

“We love his competitive nature and his willingness to learn and we look forward to seeing him continue to develop over the next few years.”

O’Brien quickly established himself as one of the dominant ruckmen in the SANFL through his first two seasons as a Crow.

He ranked third in the competition for hit-outs (561) and second for hit-outs to advantage (181) last year and finished fourth in Adelaide’s State League Club Champion count.

The 202cm ruckman played two senior games last season and featured in all three of Adelaide’s JLT Community Series matches this pre-season.

O’Brien was officially elevated to the Club’s senior list at last year’s AFL National Draft in Sydney.
