PITTSBURGH -- Dolphins defensive tackle Ndamukong Suh was not fined for a possible attempt to kick quarterback Ben Roethlisberger late in the fourth quarter of the Steelers-Dolphins game Sunday.
In the play, Suh bull-rushed guard David DeCastro and stretched his right leg out, nearly connecting with Roethlisberger's right knee before helping bring the quarterback down with his arm. The Dolphins won 30-15.
The Steelers internally flagged the play in the postgame film review and alerted coach Mike Tomlin. The Pittsburgh Post-Gazette reported Thursday the Steelers submitted the play to the NFL for review. The league's operations department had not received a Steelers request as of Thursday night, according to sources.
Suh has been fined repeated times for questionable play, including $100,000 for an illegal low block in 2013.
Dolphins head coach Adam Gase said Friday that Suh was simply playing hard and trying to make a play.
"Going back and just watching it again, I see a guy who is just playing hard and trying to figure out a way to get to the quarterback," Gase said. "So I don't know if I can comment on it past that. I just know how I've watched him play and he just goes as hard as he can."
