Mishcon de Reya has advised Matchroom Boxing on a television rights deal that has been branded the largest in boxing's history.

The eight-year deal has seen the boxing promotions company, which is led by Eddie Hearn, enter into a $1bn (£739m) partnership with sports rights company Perform Group to broadcast boxing matches on the latter's US streaming channel.

Matchroom Boxing will open a new office on Wall Street and promote 16 fights a year across the US as part of the deal. Hearn – who promotes world heavyweight champion Anthony Joshua (pictured above right) – has described the agreement as "the largest TV rights deal in the history of boxing".

US firm Dorsey & Whitney acted for Perform Group with a team including London private equity partner Carsten Greve, London/Denver corporate partner Paul Thompson and London commercial partner Ron Moscona.

Mishcon head of sport Liz Ellen, who led the firm's team advising Matchroom Boxing, said: "This is a groundbreaking deal which is likely to fundamentally change the boxing market in the US, both in terms of the promotion of top-quality boxing events and the consumption of those events via on-demand streaming.

"DAZN are seeking to become the Netflix of sport, and this deal is a key part of their strategy. If Matchroom can bring the magic and entertainment value of their UK events to the US, then sports fans have an awful lot to look forward to."

Ellen, who made partner at Mishcon in 2015, has a focus on cross-border transfer deals and disputes, sports immigration, image rights and fraud and corruption issues in sport. She worked alongside managing associate Simon Leaf on the Matchroom deal.

In February, DLA Piper took the lead role advising the Premier League on the £4.4bn sale of live TV broadcasting rights to BT and Sky. DLA has longstanding links with the Premier League, with co-CEO Simon Levine counting the league among his clients. The firm previously advised the Premier League on its 2015 rights auction sale, which raised a record £5.14bn.
