I remember seeing a trailer for a football player. He was a black football player and he had a dog and then he basically finds out he has a daughter and then she lives with him, I don't remember it much from the trailer but I believe it was released 2006-2008, around there. I tried searching it on Google but it gave me nothing. Thank you!

I believe the movie you are referring to is called, Game Plan (2007).

LOL Thank you sooo much! Im very bad at remembering names and actors, I was thinking Eddie Murphy but thank you, you are correct!

You are quite welcome.
