Junior Fa has vowed to use a family tragedy as extra motivation for his heavyweight fight against Joseph Parker in Auckland next month.
The death of Fa's cousin Vaikalafi Lutui last month from Covid-19 in Salt Lake City, Utah, has intensified Fa's focus as he counts down to the bout at Spark Arena on February 27.
Lutui, 33 when he became another victim of the pandemic on January 16, leaves behind a wife, Lota Sisilia, and four children aged under 10. The youngest, Samisoni, is 10 months old. Lutui's funeral was last Saturday.
As of this week, almost 500,000 people have died from the virus in the United States.
Vai Lutui, born in Salt Lake City, has been described as a "humble, kind giant", and played football for Kansas State University.
