Carlton forward Levi Casboult has been heavily linked with a move to Richmond next season over the past few days, but the Herald Sun reported on Friday night the Tigers will not be offering him a deal next season.

The Herald Sun believe Richmond would rather add to their list through the draft, given they have two first round selections.

Despite Richmond's need for a second tall up forward, the Tigers will not pursue Casboult, after missing out on Brisbane forward Josh Schache earlier on this season.

The Victorian was contemplating a move back home and the Tigers were seeming leading the race for Schache, before the young forward signed a two-year contract extension to stay at the Lions soon after the bye rounds.

It is also believed Richmond's deal to Dustin Martin will take up a large portion of their remaining salary cap, with the Tiger midfielder set to sign a six to seven-year contract extension worth around $1.2 million per season.

Casboult was first strongly linked to Richmond on Tuesday, after former St Kilda CEO Brian Waldron told SEN's Hungry For Sport a deal had already been agreed between the two parties.

The 27-year-old's manager then responded to their rumours on Thursday, and suggested Casboult would wait until the end of the season before surveying his options, but stressed the forward had not agreed a deal with any other club.

Casboult is enjoying the best season of his career in 2017, and has a career-best 29 goals to his name, as well as 48 contested marks, the most out of any player in the competition.
