Bolton midfielder Lee Chung-yong will be out for a minimum of nine months after breaking his leg in Saturday's pre-season friendly at Newport.
The 23-year-old South Korea international underwent a successful operation after sustaining a double fracture of his lower right leg during Wanderers' 3-1 win in south Wales. He was carried off on a stretcher midway through the first half following a rash challenge from Tom Miller.
The club posted a statement on their website confirming he was recovering in hospital and was expected to be sidelined for the bulk of the 2011-12 campaign.
Lee joined Bolton from FC Seoul in summer 2009 and has been a consistent performer for the Trotters over the past two years.
Manager Owen Coyle told www.bwfc.co.uk: "We will make sure Chung-yong gets all the support he needs, as now it is all about his recovery and wellbeing. That is the most important thing.
"The operation went well and we would like to pass on our thanks to the medical staff involved."
