Umbro, the maker of the England football team's kit, has agreed to be bought by US sportswear giant Nike in a deal worth £285m ($580m).
Nike said the deal would allow it to "significantly expand" its presence in "a key growth category" for the firm.
As well as providing kit for the England team, Umbro also supplies the kit for six Premier League clubs.
The Football Association said Nike had assured it that the FA's relationship with Umbro would be protected.
Manchester-based Umbro said last month that sales of England tops had been "disappointing ", and analysts are concerned that sales could suffer if England fail to qualify for next year's European Championship.
Brian Barwick, the chief executive of the FA, said: "We are delighted that the proposed acquisition will allow us to continue our strong historical relationship with Umbro while benefiting from the marketing expertise and financial strength of Nike."
"Nike has provided firm assurances that the FA relationship with Umbro will be protected and enhanced, and we look forward to working closely with both companies moving forward," Mr Barwick added.
