Broadband provider Sky has received the support of the Premier League in its campaign against Ofcom's proposed changes to the digital TV market.
At the end of last month, Ofcom revealed plans that would see Sky forced to cut the wholesale price it charges rival providers to offer its sports channels.
While Sky immediately described the plans as "unwarranted intervention", the Premier League has now revealed its own assessment after spending weeks mulling over the decision.
Chief Executive Richard Scudamore said the move would reduce the incentives of all broadcasters to acquire sports rights, which in turn could have major consequences for all UK sports.
"We want to see competition for our content; it attracts value to invest in what fans want – playing talent and facilities – anything that diminishes that investment will be bad for the game and bad for sports fans as a whole," he explained.
Mr Scudamore added that the Premier League had "no option" but to mount a challenge against the proposals.
