Levi Casboult and rookie Matthew Cottrell have both agreed on new one-year deals to remain with the Blues.

The versatile Casboult will enter his 11th season at the Blues with the extension, while Cottrell has been signed on after an impressive VFL campaign.

Casboult's versatility was immense in 2019, with his big physical presence and strong marking ability being used at both ends of the ground.

Known predominantly as a forward, Casboult more than held his own in the ruck and shone down back when he was thrown into the backline for the second half of the season.

Casboult won the 2019 Coaches Award as well as earn a top-five finish in the 2019 John Nicholls Medal as a result of his versatility and willingness to do whatever it was to help the team.

He delivered a career-best season in 2019, averaging six marks and three tackles per game, whilst also ranking elite in the competition for hitouts, hitouts to advantage, contested marks, marks inside 50 and tackles inside 50.

Casboult said he was thrilled to sign on for another year at the Blues.

โ€œI grew up a Carlton supporter so to extend my time at the Blues to a 11th year means I can keep living the dream,โ€ Casboult told the club website.

โ€œI have loved my time in the Navy Blue and this year I have enjoyed the different challenges thrown my way, playing forward, back and in the ruck. Most importantly, Iโ€™m really loving my footy and thatโ€™s helping me contribute.

โ€œThank you to all those who have supported me during this journey so far. Iโ€™m looking forward to the 2020 season.โ€

Cottrell will join Casboult for another year at the Blues after the 19-year-old showed promising signs for the Northern Blues in 2019.

As an elite endurance runner, Cottrell looked poised across half back and on the wing throughout his 15 VFL appearances, averaging 13 disposals and showing off his football smarts.

Carlton General Manager of List Management and Strategy Stephen Silvagni said the club are pleased to extend the contracts of Casboult and Cottrell for another year.

โ€œItโ€™s great for the Club to re-sign both Levi and Matt for the 2020 season. They both enjoyed quality 2019 seasons in their own right and we will look forward to them continuing that form moving into pre-season,โ€ Silvagni said.

โ€œLevi is a great story, after joining the Club as a rookie, he worked his way onto the senior list and has earned a 11-year AFL career. He is a great example of someone who has put in the work and is getting the most of themselves as a footballer and as a person.

โ€œMatt has shown great signs in his first year with the Club, he impressed us all with his work rate and desire to get better each and every day, we look forward to seeing him continue to develop in the Navy Blue.โ€
