Safety Chris Harris injured his hip while tackling Marshawn Lynch in the first quarter of Sunday's 35-24 win over the Seattle Seahawks at Soldier Field.
The veteran safety said he tried to play through the pain before realizing he and his teammates would be better off with him on the sideline for the remainder of the NFC divisional playoff game.
"If I couldn't be 100 percent full-speed I didn't want to be out there," he said. "I didn't want to be the guy that prevents this team from winning."
When asked if he would recover in time to play against the Packers in next Sunday's NFC Championship game at Soldier Field, he said "My ankle would have to be cut off [for me not to play.]"
