Still seems unlikely Zach Ertz plays in Eagles’ Wild Card game - San Diego Union-Tribune
Yes, we have two kidneys and a person can live a normal life on one fully functioning kidney. However, if the worst case happened and Ertz’s kidney sustained additional trauma, necessitating removal, his life would continue but his football career would be over. Typically, with one functioning kidney, one cannot play contact or collision sports. If the remaining kidney were damaged, a life on dialysis is fraught with problems. The worry on a lacerated kidney is that the “cracks” can get bigger with a second blow.
