Dean Marney has undergone successful surgery to launch his recovery from a long-term knee injury.
Marney required an operation after suffering cruciate ligament damage to his right knee in the Clarets’ defeat at Arsenal last month.
“Ally Beattie (head physiotherapist) has spoken to the specialist who did it and he was really pleased with how it went,” confirmed Burnley boss Sean Dyche.
“I spoke to Marns yesterday and he’s really pleased too.
“It’s too early to say much but it’s the first day back to recovery, that’s the way to look at it.
“It will be the slow part of the recovery now but everyone is happy that it went well.”
Marney suffered a similar injury in February, 2015, which kept the long-serving midfielder out for nine months before making a successful return to help the Clarets win promotion and then to re-establish himself as a top-flight performer.
“He has been through it before and he understands it all. He’s had a very good surgeon, so I think that helps,” Dyche added.
Dean Marney had made 221 appearances for the Clarets
The Clarets will also be without midfielders Jeff Hendrick - who starts a three-match ban - and Steven Defour for the visit of Premier League leaders Chelsea on Sunday.
Defour sustained a hamstring strain during Burnley’s 1-0 win over champions Leicester – their seventh successive home victory – on the last day of January, and has been receiving treatment in his native Belgium.
“He’s had a couple of days back in Belgium with a specialist we know, which has been helpful to him and to us,” said Dyche.
“He’ll be coming back over to continue his treatment, so he’s not ready yet.”
Meanwhile, defender Kevin Long has this week resumed training with the Claret’s first-team squad after recovering from minor knee surgery to remove scar tissue.
