Spartak Moscow fans appear to throw flare at referee
Spartak Moscow fans face possible Uefa action after it appeared that a flare was fired at the referee during their 1-1 Champions League draw away to Slovenian side Maribor.
A projectile fired from the away stand came close to hitting German official Deniz Aytekin as he walked near the halfway line.
There had been clashes before kick-off between visiting fans and police.
Spartak and Maribor are in Group E along with Liverpool and Sevilla.
Liverpool will travel to Moscow on 26 September in the second match of the campaign after drawing 2-2 with the Spanish side at Anfield on Wednesday.
