Bristol City forward Andreas Weimann has vowed to return "as soon as physically possible" after being told he needs knee surgery.
The club announced the 29-year-old Austria international could face up to nine months on the sidelines after suffering an anterior cruciate ligament injury during Saturday's 1-1 draw with Swansea.
Weimann, who will go under the knife next week, wrote on Instagram: "I'm not going to lie… I am still in shock about the news I received about my injury over the last couple of days and it hasn't quite sunk in yet.
"From pretty much not missing a game or even a training session over the last five years or so it's going to be very strange and hard not to be out there running around like a headless chicken for such a long time.
"But I'm a positive person and I know I'll be back as soon as physically possible.
"All I can do now is to support the boys and staff in any way I can to still make this a special season."
Weimann had scored two goals in seven Championship appearances this season.
Head coach Dean Holden told the club's website: "This is really sad news and we are going to miss Andi. He is a leader on and off the pitch and we will support him fully during his rehab. Everyone at the club wishes him well."
