PARIS -- France's rugby players will wear rainbow laces on their boots for Saturday's match against Fiji in support of former Wales captain Gareth Thomas, who was the victim of an anti-gay assault last weekend.

Serge Simon, the vice-president of the French Rugby Federation, wrote on Twitter that "all of French rugby is with you regarding the homophobic molestation you've been victim of."

The 44-year-old Thomas, who announced in 2009 that he is gay, played for French club for Toulouse from 2004-07 and helped the team become European champion in 2005.

Police in Cardiff said a 16-year-old boy has admitted to assaulting Thomas on Saturday. Thomas spoke about the incident in a video he recorded and had bruises on his face.
