Glasgow Warriors have suffered a blow ahead of their PRO12 semi-final against Connacht after Alex Dunbar was ruled out with a knee injury.
A scan at BMI Ross Hall Hospital revealed that the 26-year-old centre sustained a bone injury against the same opposition in their final regular-season game, with the problem not only ruling him out for his club but also his country, as Edinburgh's Matt Scott replaces him.
Scott and the rest of the Scotland squad will convene on Monday, June 6 for a short camp before their departure for Tokyo on June 11.
The two international fixtures against Japan will be played on consecutive Saturdays at J1 League football stadia; the first at Toyota Stadium in Toyota City (June 18) before the second game at Ajinomoto Stadium in Tokyo (June 25), homes of Nagoya Grampus and FC Tokyo respectively.
Glasgow released a statement saying Dunbar does not require surgery and will now begin a period of recovery with his club's medical team.
"We're disappointed for Alex that his season has been cut short through injury," said head coach Gregor Townsend.
"He had been playing very well and played a big role in getting us into the PRO12 Play-Offs.
"We wish him all the best with his rehab and we look forward to him returning to training ahead of the new season."
