Leicester Tigers back-row Steve Mafi has returned home to Australia on compassionate grounds.
The Tongan international, who grew up in Sydney, returned Down Under after complications surrounding the birth of his child.
Leicester's director of rugby Richard Cockerill said the club had given the 23-year-old time off to deal with the situation.
"He has gone home because his wife has had a baby and there are some complications there," he told the Leicester Mercury.
"He is back in Australia. We hope all is well with him and that we get him back for the London Irish game, but we will have to wait and see.
"He has some concerns with his family and he needs time to deal with those issues. We will give him that time and if that means he misses some rugby, he misses some rugby.
"Some things are more important."
