NFL takes bids for Thursday night packageAll four networks make offers for 13-week slate of games
The league has used its NFL Network to televise the games, but recently put up the 13-game series for bids. It received them from NBC, Fox, CBS and ESPN.
The person spoke on condition of anonymity because the bidders are not being made public.
Turner Sports has also bid, and there's a strong possibility ESPN would put the games on ABC should it be chosen by the league.
The NFL also has expressed a desire to simulcast the games on NFL Network.
