Fenerbahce have been banned from next season's Champions League and Besiktas from the Europa League over match-fixing allegations, UEFA has announced.
The UEFA control and disciplinary body confirmed Fener would be banned from Europe for three seasons in total, with the third deferred for a probationary period of five years.
It is the Turkish giants second exclusion from Europe's top competition after they were banned from the 2011-12 Champions League due to the match-fixing scandal.
A UEFA statement read: "The CDB carefully analysed the situation of both Fenerbahce and Besiktas and has pronounced the following sanctions:
"Besiktas is not eligible to participate in the 2013/14 UEFA Europa League.
"Fenerbahce is excluded from participating in the next three UEFA club competitions for which it would qualify, including the 2013/14 UEFA Champions League season. The ban for the third season is deferred for a probationary period of five years."
