Philadelphia Eagles tight end Zach Ertz hasn't been cleared for contact yet and it's hard to imagine he will be able to play against the Seattle Seahawks. Even though he hasn't been cleared he is expected to participate in the team's walkthrough on Wednesday according to Tim McManus of ESPN.

Ian Rapoport had reported last Sunday that Ertz is dealing with a cracked rib and a lacerated kidney. The kidney is a serious issue and something the team needs to be very careful about.

According to UpToDate via Cody Benjamin of CBS Sports, Ertz could be at risk of losing the kidney even if he does rest and doesn't injure it more.

According to UpToDate, a resource tool for physicians and patients, a lacerated kidney puts Ertz at risk of losing his kidney regardless of whether he returns to the field during the Eagles' potential playoff run. Depending on the severity of the injury, Ertz might be recommended to rest from contact sports for at least a month — perhaps even six weeks, at the minimum, according to a medical source — meaning an end to the tight end's 2019 season

If Ertz had shown signs of internal bleeding or raised blood pressure, the doctors would probably already removed his kidney. With all the issues surrounding the kidney and the risk of playing it's hard to imagine the doctors are going to clear him for contact. That is a big loss for the Eagles but they were able to overcome it in the teams Week 17 victory over the New York Giants.
