Millwall legend Neil Harris has shown his softer side, posing in a furry moustache with team-mates Zak Whitbread and Chris Hackett to support the Everyman Campaign's TacheBack fundraiser.
Chopper posed with the tache to encourage men to take part in TacheBack this September and get growing for vital research into prostate and testicular cancer.
He is helping the charity raise around £300,000 this year, taking the overall figure raised by the fundraiser to over £1million.
Harris has supported Everyman, the UK's leading male cancer campaign, since he was diagnosed with testicular cancer in 2001. 
Chopper said: "A lot of Millwall fans have supported Everyman in the past as they know how important the charity is to me.
It would be great if they decided to grow a sponsored moustache too. Everyman does really good work to find treatments for prostate and testicular cancer, diseases which affect around 37,000 men every year in the UK."
With a new warrior theme, this year's competitors are invited to enter the 'arena' and compete against other hairy warriors from across the UK, either as an individual or as part of a tache team.
Male shaving and grooming brand, Remington, is a strong supporter of TacheBack and has provided another great incentive to get involved by supplying grooming goodies to one lucky TacheBack winner.
TacheBack spokesperson, Sarah Healy said: "Neil and his fans are brilliant supporters of the charity and it would be great to see loads of tached men in the stands this season. And even if you can't grow a moustache, you can download a tache for your mobile and help us on the way to reaching our £1 million target!"
To take part in TacheBack simply register online at www.tacheback.com or call 0800 731 9468. Visit www.tacheback.com/mobile to download a tache for your phone.
Any Millwall fans taking part can also send in their tache-tastic photos to questions@millwallplc.com and the club will post them on a special Lions TacheBack picture gallery.

It was founded in 1909 to carry out research into the causes of cancer and to develop new strategies for its prevention, diagnosis, treatment and care. Website is at www.icr.ac.uk

* Prostate cancer has overtaken lung cancer to become the most common cancer in men affecting almost 35,000 men every year in the UK. One man dies of prostate cancer in the UK every hour.

* Testicular cancer is the most common form of cancer in men aged between 15 and 44, with about 2,000 cases a year in the UK.Incidence is increasing dramatically - by almost four-fold in the past 50 years, but thanks to advances made at Everyman, testicular cancer is 99 per cent curable if caught early, and with treatment the overall cure rate is 95 per cent.
