Celtic winger Yang Hyun-jun will miss the champions' next four fixtures after being called up for South Korea's Asian Games campaign, a notable blow given his rediscovered form. Once close to leaving for Birmingham City in January, the 24-year-old signed a new contract until 2030 in the summer and has continued scoring key goals this season, prompting captain Callum McGregor to describe him as "a really important part of the team" while wishing him well for the tournament.

Yang scored the winner in Celtic's 2-1 victory at St Mirren on Saturday, his second goal in three days after also netting against Aberdeen, taking his tally to two goals and an assist in seven games this season, following 10 goals and three assists last term. South Korea face Qatar and Saudi Arabia in Japan later this month, while Celtic must navigate St Johnstone, a League Cup quarter-final at Rangers, a home Europa League tie with Ferencvaros and an Old Firm derby without him; Sebastian Tounekti, who deputised in Paisley, and the returning Jota offer squad depth, though pundits acknowledge a likely drop-off in his absence.
