Promising Adelaide small forward Tyson Stengle will follow family tradition and inherit the No.18 Crows jumper that's been left vacant by former favourite son Eddie Betts.

One of the most cherished Crows players in the club's history, with 310 goals in 132 games, Betts wore the No.18 jumper for six seasons before requesting a trade back to Carlton during last month's NAB AFL Trade Period.

But he's assured supporters that the famous number is in good hands, passing it on to his 21-year-old cousin.

Another of Betts' relatives, former defender Graham Johncock, wore the No.18 jumper for the Crows for 227 games between 2002 and 2013.

"Tyson Stengle (will be) jumping into the No.18," Betts told radio station FIVEaa.

"We want to keep the number in the family because Graham Johncock … is a Betts, I'm a Betts and Tyson Stengle is a Betts as well, so it's true family ties."

Stengle played two games for the Crows this year, kicking five goals.

He wore the No.17 jumper this season in his first year at the club having started his career at Richmond.
