West Coast and Richmond have both made cuts to their train-on list just under two weeks out from the start of the season.

Clubs have until March 9 to sign players via the pre-season supplemental selection period.

According to AFL Media's Nathan Schmook, the Eagles will keep Daniel Venables as an 'active player', meaning ex-Lion Cedric Cox and Swan Districts defender Will Collins will have one more week training with the club.

They follow Subiaco forward Nick Martin in finishing up with West Coast, who was also trialing for a list spot before suffering a strained quad.

The Eagles would need to place Venables as 'inactive' to open a list spot, but Schmook reports that he is likely to remain eligible for selection.

Meanwhile, Richmond have reportedly confirmed West Adelaide midfielder Nic Couroupis' release as a train-on player, who will now remain in the SANFL for 2021, per The Age's Daniel Cherny.

Couroupis played in Richmond's scratch match against the Demons last week as one of several players hoping to win a spot on the reigning premiers' list.

It leaves defender Derek Eggmolesse-Smith, utility Josh Green and former Crow Jordan Gallucci as Richmond's remaining train-on players vying for the final spot.

The trio will reportedly train with the Tigers for another week in a bid to secure an AFL lifeline ahead of next Tuesday's pre-season supplemental selection period deadline.

Richmond already filled one of their two rookie list spots in signing Tasmanian defender Rhyan Mansell.

It follows news yesterday that North Melbourne had cut ties with train-on players Flynn Appleby and Sam Skinner.

Clubs can also hold list spots over to the June 2 mid-season draft.
