San Jose: Jarryd Hayne has become the third player associated with the San Francisco 49ers to have allegedly committed a sexual assault on a woman who had been taken home from San Jose nightclub, The Willow Den.

On Wednesday, court documents filed in the Santa Clara County Court revealed Hayne was the subject of a civil lawsuit, alleging he had raped a young woman while he was in the US playing for the 49ers.

Hayne is understood to have met the woman, known as "Ms V," at The Willow Den on Lincoln Avenue in San Jose, before allegedly taking her back to his apartment and having non-consensual sex.

Fairfax Media has revealed it is the same nightclub in which former 49ers defensive end Ray McDonald met and shared drinks with a young woman, before allegedly taking her back to his house. He was subsequently fired by the club.
