Liverpool forward Raheem Sterling has missed training for a second successive day.
Press Association Sport understands the 20-year-old has reported in sick again, having initially failed to attend on Wednesday.
It is understood that Sterling spoke to manager Brendan Rodgers earlier this week and informed him that he did not want to travel on the pre-season tour.
The squad are due to fly out on Sunday ahead of their first friendly against a Thai All Stars side in Bangkok next week.
Sterling has been the subject to two failed bids from Manchester City, the last an offer of £40million, and they continue to monitor the situation.
