St Kilda coach Alan Richardson may again use Nick Riewoldt on the wing against the Crows on Saturday after the veteran starred in the Saints' remarkable second-half comeback against the Western Bulldogs in Round Six.

St Kilda was 55 points down against the Bulldogs early in the third term, but the Saints fashioned the equal-fifth greatest comeback in VFL/AFL history, with Riewoldt working up the ground to help supply Jack Billings, Josh Bruce and Tom Hickey in attack.

Richardson told reporters on Tuesday that Riewoldt would be alternate between the forward 50 and the wing for the rest of 2015.

"You've got to remember there's been a bit of noise that with Nick out of [attack] it helps the other two boys, but the reality is that against Gold Coast Nick was predominantly forward and we were still able to kick a big score," Richardson said.

"We don't really care who scores as long as the team scores.

"Nick going up on to the wing (against the Bulldogs) was much more about the fact that we couldn't get out of defence.

"He'll mix between playing high as a forward or playing deep."

Richardson said the Saints faced a "great challenge" to back up their comeback win against the Bulldogs when they clash with Adelaide at Adelaide Oval on Saturday.

The Saints coach said the Crows would be a good measuring stick of how much his team had improved since Adelaide smashed it by 86 points in Round Four last year at Etihad Stadium and by 79 points in Round 23 at Adelaide Oval.

"There was no doubt that what we were able to get out of the weekend was 'Righto, if we turn up and we're poor in the contest and we're not prepared to run and work for our mates then we're going to be pretty average'," Richardson said.

Richardson also said veteran defender Sam Gilbert was "really close" to returning to the senior team after playing two of the past three VFL rounds for Sandringham.

A succession of foot injuries has sidelined Gilbert for all bar 15 senior games since the end of 2012.
