LATROBE, Pa. -- Steelers running back Rashard Mendenhall sat out the team's afternoon workout after having his toe stepped on earlier in the day.
Coach Mike Tomlin said Mendenhall was held out during the second of Monday's two practices for precautionary reasons. The injury is not believed to be serious.
Five-time Pro Bowl nose tackle Casey Hampton practiced in a limited capacity after missing the first two days of training camp with a hamstring injury.
Second-round draft pick Jason Worilds also injured a hamstring, the same injury that sidelined rookie offensive lineman Maurkice Pouncey and running back Jonathan Dwyer. Both were injured on Sunday -- Pouncey while doing a conditioning run that Tomlin wanted.
Pouncey, the Steelers' first-round pick, is close to returning.
