Rangers submit evidence to Uefa
Rangers have made initial submissions to Uefa ahead of the disciplinary hearing they face on 12 April.
Allegations of bigoted chanting from Rangers fans during their Champions League ties with Villarreal will be examined by Europe's governing body.
And an incident in Spain saw the Villarreal team bus attacked.
A Rangers statement said: "The club has lodged both written submissions and material productions in response to the proceedings instigated by Uefa."
Rangers are not allowed to send a representative to argue their case at the hearing in Nyon, Switzerland.
And it is understood that the Ibrox club have detailed the efforts being made to eradicate the problem of sectarianism among sections of their followers.
Rangers bowed out of the last 16 stage of the Champions League on the away-goals rule, following a 2-2 draw at Ibrox and a 1-1 draw in Spain.
Following the second-leg tie at the El Madrigal Stadium, a statement on the Uefa website said: "The European governing body will give attention to the improper conduct and hooliganism of Rangers supporters in the return leg in Spain on 7 March, as well as to the fans' discriminatory chants in both fixtures.
"Villarreal are also being investigated for lack of organisation and violation of Uefa security instructions in the return leg match."
