Barcelona midfielder Sergio Buquets will miss his club's next two Champions League games after being banned by UEFA following his red card against Benfica last week.
Busquets, 24, was sent off by referee Cuneyt Cakir in the latter stages of Barca's 2-0 victory at the Estadio da Luz - receiving his marching orders in the 88th minute for a rash challenge on Benfica captain Maxi Pereira.
And UEFA has now ruled that he will be suspended for the upcoming Champions League double-header against Celtic, who travel to Camp Nou on October 23 before hosting the Catalans at Parkhead on November 7.
Barcelona are top of Group G having won both of their opening fixtures, with Tito Vilanova's side narrowly beating Spartak Moscow 3-2 at home and following it up with victory in Lisbon.
UEFA has confirmed Busquets appeal against the disciplinary panel ruling within three days.
