As previously reported, the Pittsburgh Steelers were without the services Thursday of linebackers James Harrison and Ryan Shazier as both players missed the voluntary practice for undisclosed reason. In addition to those two players, it appears as though four more sat out the final session of the second weeks as well.
According to Chris Bradford of the Beaver County Times, quarterback Bruce Gradkowski, tight end Matt Spaeth, tackle Kelvin Beachum and tackle Mike Adams were all present Thursday but did not participate in practice.
