Milestone man Luke Brown has added to his big week by signing a three-year contract extension.

Brown, who is set to play his 100^th game, will remain at Adelaide until at least the end of 2020.

Recruited from Norwood, Brown became a Crow in the 2011 exchange period after being on-traded by Greater Western Sydney.

Brown negates the best small forwards in the AFL on a weekly basis, and leads the Club for disposal efficiency (84.6 per cent) in 2017.

The consistent Crow said it was an easy decision to sign on.

“I am excited to be able to continue my career at the Crows,” Brown said.

“It’s a great environment to be around at the Club and we have a determined playing group that I feel is not far off success.”

Crows General Manager List Management and Strategy Justin Reid described Brown as an integral member of the Club’s defence.

“We are thrilled to have Luke re-sign with us,” Reid said.

“He is a key part of our back six and works in really well with our defensive group.

“He is a developing leader amongst the playing group and we love his competitive nature and team-first approach.”

As durable as he is reliable, Brown has played 96 of Adelaide’s last 99 games.

He received a Rising Star nomination in 2013 and was also recognised internally with the M.A Bickley Award for Emerging Talent.

Brown said he didn't consider testing his value on the open market.

"It was a great opportunity to stay at this Club, we're in a great spot right now and I'm really happy with how the team is going," Brown said.

"Ever since I got to the club, I'm an Adelaide boy, so it's good to show the faith and stay here for another three years.

"I didn't look outside of the club, I wanted to talk to the club and they rate me really highly.

"They value the role I play and that's really important to me."

After having won their first six games of the season, the Crows have thudded back to earth with back-to-back losses to North Melbourne and Melbourne.

"The last two weeks the pressure has been intense; we just need to handle that better," Brown said.

"It starts on the contested-ball side of things.

"It's more a mental thing more than anything.

"If you look at our midfield, they are all tough guys, they win the ball in and under, so we just have to get back to what we do best."
