Winless Adelaide players have insisted coach Neil Craig radically alter his training regimen for the rest of the AFL season.

As the club grapples with final quarter fade-outs and an injury toll of 14 players, Adelaide's leadership group has won significant reform of Craig's methods.

Renowned for being among the league's toughest trainers, Craig has agreed to ditch their customary match-eve training for the remainder of the season.

And the club's main training session has been split into shorter 90-minute sessions over two days, Wednesdays and Fridays, rather than the current one longer session.

"It is just a bit of variation, we sometimes fit a lot into our main session but now we have broken it up into two different training sessions per week," Crows midfielder Brent Relly said on Monday.

"The leadership group approached the coaching staff and they worked it out."

The Crows have not won a final term this season, conceding 24 goals and kicking just eight in last quarters.

The training tweak acknowledges something had to give amid Adelaide's worst start to a season, six consecutive losses.

Reilly said the abolition of match eve training sessions would freshen players' minds and bodies.

"It's going to be interesting to see how we go about it, but I am sure it will be good for us, to have a lighter day of training before we play ... I'm looking forward to it," Reilly said.

"It can get quite, what is the word, boring - doing to same stuff every week, so it's good to throw in a different program, everyone looks forward to the change."

The Crows rate wingman David Mackay (groin) and forward Chris Knights (foot) only slight chances of returning for Adelaide's home match against the AFL's other winless club, Richmond, on Sunday.

Utility Patrick Dangerfield (hand) and ruckman James Sellar (hamstring) remain two weeks from action while the Crows still have five players sidelined indefinitely with knee problems - Andy Otten, Brad Symes, Trent Hentschel, Brad Moran and Brodie Martin - and another four out with hamstring strains.
