The San Francisco 49ers have increased their stake in Leeds United to 37% - the Premier League club have announced.
Paraag Marathe, the president of 49ers Enterprises who was already a member of the Yorkshire club's board, becomes the Whites' vice-chairman.
Leeds chairman Andrea Radrizzani said:
"We are delighted to welcome further investment into our club from 49ers Enterprises and I am confident that this latest partnership will help Leeds United continue to grow and develop into the team our supporters deserve.
"I have always been open to bringing partners on this journey with me, as long as these actions can benefit the long-term strategy of the club."
The 49ers bought an initial 15% stake from majority owner Radrizzani in 2018.
Leeds' announcement said Marathe would be "more involved in the decision-making process and day-to-day operations" following the increase in the 49ers' stake.
