Ben Roethlisberger is concerned about the Pittsburgh Steelers' physical practices affecting the health of players.

The Steelers are expected to face the Miami Dolphins on Sunday without three of their most talented defensive players -- Cam Heyward (hamstring), Ryan Shazier (knee) and Bud Dupree (sports hernia).

"When you're doing it over and over and the guy's shoulders are getting sore and knees start getting sore and hips and hamstrings and quads and things, and then they re-occur, you've got to maybe take a look at what you're doing," Roethlisberger said.

"We pride ourselves as the Pittsburgh Steelers being a physical football team, so it's a fine line you have to walk."

Roethlisberger said on his weekly appearance with 93.7 The Fan that physical practices might be taking a toll on the roster. He referenced the joint practices with the Detroit Lions in August, when Detroit was undergoing its first live hitting session while the Steelers had been hitting for two weeks.

All NFL teams are limited to 14 padded practices per regular season, but the Steelers are known to have one of the most physical training camps in the league.
