Johnson lost the top of his left middle finger after tackling the Saints' Darren Sproles on a punt return.
Johnson came to the sideline after the play with a finger injury. When he took off his glove, the tip of his finger remained behind. The tweet below says it was his right hand, but it was actually his left.

Cardinals S Rashad Johnson unsure when he lost top portion of his finger. Thinks it was on a punt return, but needs to watch film.— Adam Schefter (@AdamSchefter) September 23, 2013
He then stayed in the game after the injury. Johnson had surgery after the game to shave his finger down to the first knuckle, according to the report. The bone was exposed so infection is a possible concern.
