Roma has confirmed that forward Gervinho will be sidelined for up to three weeks because of a thigh strain.

The Cote d'Ivoire international was forced off after 72 minutes of his country's 3-0 World Cup qualifying win over Liberia on Wednesday and underwent further tests in the Italian capital.

The club has since announced that the injury is likely to keep him out of action for three weeks, meaning he will miss the crucial Champions League clash with Barcelona at Camp Nou on 24 November and is a doubt for the final group-stage game with BATE on 9 December.

The former Arsenal attacker will also miss Serie A games with Bologna, Atalanta and Torino.

Roma is already missing Mohamed Salah because of an ankle problem picked up in the derby win over Lazio.

Rudi Garcia's side sits second in Champions League Group E after four matches, just a point ahead of Bayer Leverkusen, while it is third in Serie A heading into this weekend's fixtures.
