However, despite rival clubs hovering as trade talks heated up in Canberra during the final days of the NAB AFL Draft Combine, Carlton is still trying to convince Grigg to change his mind and remain in the navy blue.
Grigg rang Blues football manager Steven Icke on Thursday to tell him of his desire to be traded, with the club later issuing a statement on its website confirming the 22-year-old's decision.
But 24 hours later Carlton hadn't given up hope of retaining Grigg.
Should the former North Ballarat junior go through with his plan to leave Brett Ratten's side, the Tigers are waiting to strike a deal.
"We've had a chat to Shaun," Richmond recruiting manager Francis Jackson told afl.com.au.
"We think he's got lots of exciting traits and perhaps hasn't played the best he possibly could have, for one reason or another, over the past 12 months."
Tigers coach Damien Hardwick is overseeing almost a complete rebuild of his club's list, and while certain players in trade week won't fit Richmond's criteria, Grigg does.
"He's still young enough," Jackson said.
"He's the 2006 draft, same as Jack Riewoldt, so he's 21, 22. He fits in that age bracket of kids coming through."
Jackson said Hardwick was determined to continue transforming the Tigers' list and, as such, the club was unlikely to trade away its early picks in this year's NAB AFL Draft.
"We got 14 new players last year ... and we'll probably have another eight or nine this year given our national draft picks and rookie list, so in essence that's 50 per cent of your list in two years," he said.
"As a recruiting manager who goes to the footy all year long, I want to hang onto most of them.
"So we're going to be very, very young having lost the experience that we did last year."
Jackson confirmed several clubs were interested in contracted midfielder Richard Tambling, with the Adelaide Crows among them.
"I've had a chat to them and the possibility [of a trade] and we'll see what comes and what eventuates at the end of the day," he said.
"There's plenty of to-ing and fro-ing at the moment, so obviously you need to strike that healthy balance before something eventuates."
