NYON, Switzerland - UEFA says it has opened disciplinary proceedings against FC Basel after the Swiss side's fans threw fireworks onto the pitch during a Europa League match against Salzburg, causing a brief suspension of play.
The incident occurred in the first half of Basel's 2-1 victory in the last-16 second leg in Austria, which put the team through to the quarter-finals.
The match referee decided to take the players off the pitch for about 10 minutes.
UEFA says in a statement on Friday that Basel was being disciplined for the "setting-off and throwing of fireworks and improper conduct of the team."
UEFA's control and disciplinary body will deal with the matter on Wednesday.
