Owen Coyle was delighted to see the winger back at Euxton on Monday but admitted he's still a long way away from returning to match actionLee Chung-Yong has returned to full training with Bolton after almost 10 months out due to a broken leg suffered in pre-season.
The 23-year-old South Korea international, who suffered the injury in a pre-season friendly against Newport, resumed full training with the Bolton squad at the club's Euxton ground on Monday.
Bolton manager Owen Coyle told the club's website it was a positive sign to see him back, but admitted he wasn't ready for a return to match action anytime soon.
"It's one thing to start training and it's another thing to be fit and available for the games, but it's great to have Chungy back out on the grass with our group," Coyle said.
"It's encouraging to see him have that smile again and hopefully he will give a lift and boost to our squad."
Lee, who won Bolton's Player of the Year in 2010 after joining the club from FC Seoul, will also hope to be fit for his country's fourth round 2014 World Cup qualifiers which begin in June.
