Brentford are set to be without forward Yoane Wissa for 'a couple of months' with an ankle injury, manager Thomas Frank has confirmed.
Wissa opened the scoring inside opening 30 seconds against Manchester City on Saturday, but was then substituted just before half-time following a challenge with Mateo Kovacic.
Speaking ahead of Tuesday's Carabao Cup tie against Leyton Orient, Frank confirmed Wissa was set for a spell on the sidelines.
'Wissa is not good news. It looks like an injury that will be a couple of months,' Frank said at a press conference.
'It is very frustrating. It will leave a hole, but I will find a solution and other players will step up.'

Brentford are already without summer signing Igor Thiago, who has a knee problem, while England striker Ivan Toney left for Saudi Pro League club Al-Ahli ahead of the transfer deadline.
Frank added: 'It will leave a big hole. Everybody was saying we bought Igor Thiago to replace Ivan (Toney) - but we still had Wissa.
'We bought Igor Thiago to build the squad and provide competition in the squad.
'Wissa had a very good season last year and I thought he has started the season very well this year, with three goals in four games, that's a very good number.
'He's just been very important for us and that's going to leave a hole. But, again, I will find a solution.'
