is there a way to watch current football games online?

my dad wants to watch current football games, as they're on tv, but on a laptop. i'm pretty sure there's websites for older games but i'm not sure about games that are new, like on game day. he wants to watch these games online. please if you could list some websites where this is possible or even help by telling me what to search. because i dont want to stream old football games. i hope i'm making sense, i'm just tryin to help my dad, he works during the games and by the time he gets home its time to go to bed. yes he works all day. (owns a restaurant) so he can't record a game and watch it later.
