Miami Dolphins quarterback Tua Tagovailoa (1) carted out the field after getting injured in a play during the first quarter of an NFL football game against the Buffalo Bills at Hard Rock Stadium, Sunday, Sept. 19, 2021 in Miami Gardens, Fla. A battery of tests run on Tagovailoa failed to show any serious problems other than bruised ribs, raising at least the possibility that he could play next weekend when the Dolphins (1-1) visit the Las Vegas Raiders (2-0).
