Steelers' David DeCastro doesn't care if Ndamukong Suh is dirty: 'He's a great player'

PITTSBURGH -- One of the top players on the Pittsburgh Steelers' scouting report has a way of rankling opponents.

But the Steelers don't seem concerned with Miami defensive tackle Ndamukong Suh's antics entering Sunday's AFC wild-card game. Pro Bowl guard David DeCastro, tasked with blocking Suh on Sunday, said "I don't really care" when asked whether Suh straddles the line of being a dirty player.

New England running back LeGarrette Blount cares. He called Suh "dirty" after a scuffle with Suh in Sunday's Patriots win. And in Week 6 against Pittsburgh, Steelers coaches weren't pleased with a late-fourth-quarter play that showed Suh kicking in the direction of Ben Roethlisberger's leg.

"If you can block him and keep him away, that's the only thing I can control," DeCastro said. "If I can do that, hopefully that stuff doesn't happen. It's a tough job. It will be a good challenge for us."

Suh, who has incurred several NFL fines for questionable play during his seven-year career, is one of three Dolphins defenders with at least five sacks this season.

The Steelers' 30-15 loss to Miami on Oct. 16 was one of their worst offensive performances of the season with 267 total yards. Roethlisberger left the game with a knee injury that required minor surgery the following day.

The Steelers' offensive line -- which allows 1.3 sacks per game, one of the league's best clips -- takes pride in helping each other instead of relying solely on one-on-ones. DeCastro will get some help on Suh. But he'll be matched up with the behemoth early and often, and he's prepared for limbs to fly.

"That's who he is -- he's a great player," DeCastro said. "He's always trying to create havoc, create pressure. It's our job to stop him."
