Ted Wells' law firm billed the NFL more than $2.5 million to investigate deflategate.

Asked during the appeal how much he was paid for the report, Wells said "the paid question is interesting" and clarified he will likely bill the NFL more than $2.5 million.

"For the report, through May 6th, it's somewhere in the area -- and I'm not sure the bill was out, but it's going to be around somewhere in the range of $2.5 to $3 million," Wells said.

Wells anticipates future additions to the bill.
