The Patriots' defense took a blow in the beginning of the second half of Super Bowl LIII.
Safety Patrick Chung went down with an arm injury less than a minute into the third quarter. During a play, his right arm was caught between the helmets of Rams running back Todd Gurley II and teammate Jonathan Jones.
Chung's arm was put in a cast and he walked off the field, not getting in the cart that was taken out to the field for him.
