It was recently discovered that Madden NFL 19, which is available now for EA and Origin Access subscribers before its public release, removed Colin Kaepernick's name in the YG song "Big Bank" featured on the game's soundtrack. The line is supposed to be "You boys all cap, I'm more Colin Kaepernick." However, his name was scrubbed from the verse sung by Big Sean, leading to a really strange edit that caught the attention of pre-release players.

EA has now explained that it was an "unfortunate mistake." According to EA, some of its developers did not believe they had the rights to Kaepernick's name, so that's why it was censored out of the song. EA indeed does not have the rights to Kaepernick, as he's not signed to any NFL roster, but this doesn't apply to the soundtrack.
