ADELAIDE has extended the contract of key position prospect Elliott Himmelberg for two more years, until the end of 2020.

The 19-year-old – who stands 198cm and was the 51st overall pick of the 2016 NAB AFL Draft - showed glimpses of his potential in the SANFL last season.

"The club has been fantastic to me ever since I first arrived," Himmelberg said.

"I’ve settled in nicely to Adelaide and I’m stoked to be able to play footy here for another couple of years at least."

Crows list manager Justin Reid said Himmelberg was an exciting player for fans to look out for in the future.

"Elliott is a key position type with some good skills for a player his size, he has transitioned into our football program well and we are thrilled to have him commit to Adelaide for a further two years," Reid said.

"We have been really impressed with him since his arrival at the club and his attitude and application to training this pre-season has been fantastic.

"We are really excited to watch him develop as a player and as a person over the next few years."

Himmelberg is the younger brother of Greater Western Sydney forward Harry Himmelberg.

Playing predominately as a forward, Himmelberg booted 19 goals in his 13 SANFL games last year, including a bag of four against Port Adelaide.

He was troubled by a foot injury at the end of last season, but is back to full fitness and was impressive in a SANFL trial against West Adelaide a couple of weeks ago.
