Two-time Ballon d'Or winner Alexia Putellas and two of her teammates in Spain's women's national team appeared before a judge Monday as witnesses in the investigation of former federation president Luis Rubiales for his unsolicited kiss on forward Jenni Hermoso.

Putellas, Irene Paredes and Misa Rodríguez all answered questions from the judge in Madrid. Rodríguez appeared in court in the Spanish capital, while Putellas and Paredes testified through video conference from Barcelona.

Spanish state prosecutors have accused Rubiales of sexual assault and coercion for kissing Hermoso on the lips without her consent during the awards ceremony after the Women's World Cup final in August.

A couple of federation officials and former national team coach Jorge Vilda, who was replaced not long after winning the World Cup in Australia, have been summoned as investigated parties. They are set to appear before the judge next week. Vilda was among those accused of allegedly trying to convince Hermoso to back Rubiales after the kiss.

Rubiales eventually resigned, and the players ended their boycott of the national team after being given some guarantees of change within the federation. Some federation officials have already been fired as a result.

Hermoso is also expected to testify at some point.

According to a sexual consent law passed last year, Rubiales could face a fine or a prison sentence of one to four years if found guilty of sexual assault. The new law eliminated the difference between "sexual harassment" and "sexual assault," sanctioning any unconsented sexual act.
