In return, AEG pledged to build a "green stadium" and make it public-transit friendly.
Earlier in the week, Leiweke addressed reports that the company and the NFL were at odds over team ownership and stadium revenue, saying developer Philip Anschutz is willing to buy a team himself in order to make the deal work.
Leiweke told the Los Angeles Times that Anschutz is ready to write a check for both the downtown stadium and a team as long as he can get a "reasonable" deal out of the football league.
Reports, including one from Yahoo sports, said the NFL was unhappy with Anschutz's proposal that he own just a small part of the team but collect stadium revenues usually reserved for owners.
Leiweke has said he has spoken with several teams about moving to Los Angeles, but declined to specify which ones. He said he plans to follow the guidance of NFL Commissioner Roger Goodell about which teams would be candidates.
