The Adelaide Crows have re-signed talented quartet Riley Knight, Jake Kelly, Alex Keath and Tom Doedee.

The four emerging young stars have all signed two year contract extensions, keeping them at the club until the end of the 2019 season.

Knight has played 26 games for the Crows since being selected in the 2013 National Draft. Kelly has played 28 games since making his debut in 2015.

Keath, a promising junior who joined the club after playing cricket for Victoria for four years, has played four games after making his debut in Round 18, while Doedee, recruited in the 2015 National Draft, is yet to make his debut.

“It’s a great reward for Riley, Jake, Alex and Tom,” Adelaide General Manager of List Management and Strategy Justin Reid said.

“All four are very team-orientated players, who are willing to do whatever it takes to help the Club succeed and we look forward to seeing them continue to grow.

“We have developed a learning environment at Adelaide where we want to give players every chance of getting the best out of themselves.”

The Crows are still yet to re-sign in demand young gun defender, Jake Lever.
