PITTSBURGH (93-7 The FAN) – An officiating crew was again on hand for practice Wednesday afternoon when the Steelers began their on-field preparations for Sunday’s game in Cleveland.

It’s the second week in a row that Mike Tomlin has had officials oversee practice. The Steelers were penalized seven times against Jacksonville and continue to be the NFL’s most penalized team through five games.

Four players were given the day off: defensive end Brett Keisel, tight end Heath Miller and safeties Troy Polamalu and Micheal Mitchell. Safety Shamarko Thomas missed practice with a hamstring injury, while cornerback Ike Taylor (forearm) and linebacker Ryan Shazier (knee) remain out.

Shazier, who sprained the MCL in his right knee on Sept. 21, ran on the grass for the first time since the injury.

“Normally, I’ve been in the pool, but today I was on the field and did some extra running,” he told 93.7 The Fan’s Eric Hagman after practice. Shazier added, “I feel good, but I’m not 100 percent.”

Tomlin said during his Tuesday press conference that Shazier could practice soon. The rookie linebacker said he’s taking it “day to day” and doesn’t want to risk reinjuring the knee.
