Ben Roethlisberger appeared in a walking boot on his right foot after Sunday's 30-12 win over the Miami Dolphins in the AFC wild-card.

Roethlisberger said he doesn't know the nature of the injury but he expects to play next week at the Kansas City Chiefs.

"We will find out soon, hopefully," Roethlisberger said. "You're always worried about being hurt, but I'll be out there next week."

Roethlisberger suffered an injury on his final play of the game. With 4:34 left in the fourth quarter and the Steelers up 30-12, Roethlisberger attempted a pass while on the move. The ball was intercepted by cornerback Xavien Howard, and Roethlisberger was slow to get up. The Steelers had taken Le'Veon Bell out the game at that point.

When asked whether he was surprised he was still in the game, Roethlisberger said he was not, adding "I love being out there with the guys."
