Carlton forward Levi Casboult has signed on for another two years at Visy Park.
The 22-year-old rookie, who was elevated to the senior list this week, played the last six games of the season after injuring his knee in the opening round of the VFL.
He fought his way back into contention but suffered a setback when he re-injured the knee.
Casboult made his debut against the Western Bulldogs in Round 17 replacing injured Blues Matthew Kreuzer, Rob Warnock and Shaun Hampson.
“The contract offers security, but it doesn’t really change anything,” Casboult told the club website.
“I’ve still got to work hard to keep my spot in the 22 and I know there’s a lot of hard work ahead.
“Going down with injury at the start of the year, I never thought I’d get to this stage where I’d sign a two-year contract,” he said.
“I was always confident I could get back, but there were times when I was in (rehab) by myself or with two or three other blokes in there at eight o’clock on a Sunday morning and thinking, ‘What’s going on here?’”
Carlton assistant coach Gavin Brown likened Casboult’s marking ability to former St Kilda great Stewart Loewe.
“He’s got vice-like hands a beautiful big jump on him,” he said.
“It’s well documented that he’s just got to work on his goalkicking.”
