UEFA rejects Lazio appeal
The Aquile lost their appeal to UEFA to lift the ban after disagreeing with the verdict.
The Stadio Olimpico outfit were also fined €40,000 on top of this.
The ban that is now imposed will mean that the Stadio Olimpico will be empty when Lazio host Stuttgart on 14 March in the second leg of their last-16 tie in the Europa League with a 2-0 lead from the first tie.
Lazio advanced over Mönchengladbach with 5-3 on aggregate following a 3-3 draw in the first leg .
