COACH Mummy. That's how Greater Western Sydney ruckman Shane Mumford plans to get himself over the heartbreak of his season-ending ankle injury.

The Giants' finals chances took a massive hit when their No.1 big man went down in the round 11 loss to Collingwood, which also saw co-captain Phil Davis and fellow key defender Joel Patfull suffer long-term injuries.

Mumford is widely renowned as the Giants' most important player, but rather than dwell on his surgery, the joker will step up his mentoring role with back-up rucks Tom Downie, Rory Lobb and Andrew Phillips.

Between them, the trio has played just 17 senior games, but Lobb and Downie more than held their own against Richmond last week.

"I'm going to try and turn myself into a ruck coach, I've got to do something with this next six months, so if I can do that and look towards life after footy as well," Mumford told AFL.com.au

"I'll put my two cents in, I've already spoken to Tom (Downie) and Rory (Lobb) about doing some stuff with them from the vision from the weekend, there's a few things I saw that I want to have a chat with them about.

"If I'm able to help out with these young guys coming through, and if I can have a positive impact on them it's obviously going to help us this year, and going forward.

"What we saw on the weekend is what we can expect in the future and there's obviously a few things we want to tidy up with their games, but their effort and energy on the weekend was brilliant."

The Giants were 7-3 and playing for a to- four spot when they met the Magpies, but lost that game, and subsequent games against North Melbourne and the Tigers, but Mumford bristled at suggestions his side's charge towards an historic first ever finals campaign is hopeless.

"You never want to hear that about your team, but with the amount of guys we've had waiting in the wings, there's been plenty of guys ready to step up and take their opportunity," Mumford said.

"We've seen the guys that have come in and played their role, it's always going to be tough when you lose so many key players in one game, but it's just me that's out for the year and there's no reason we can't push towards the finals."

With the help of GWS chairman Tony Shepherd, Mumford now has a buggy to keep him mobile while his ankle recovers.

But he'll be in a moon boot for at least another five weeks, and won't be up and running until season 2015 is well and truly over.

On a positive note, the popular clubman will be ready for day one of the Giants' pre-season campaign; he just needs to get through the next few months as a frustrated spectator first.

"It's going to be a long, slow process, I don't have any pain now, it's just about letting things heal before I can put any weight through there," Mumford said.

"I'm not the best at watching blokes play, when you see things where I think I could have had an impact in games, you get a bit angry.

"My girlfriend is hating it because when we're watching on TV I'm yelling half the time, but it's just a challenge for me to get it right and come back bigger and better next year."
