ALLEN PARK, Mich. -- Ndamukong Suh has been fined again.

The Detroit Lions defensive tackle was fined $31,500 for a hit on Cleveland Browns quarterback Brandon Weeden last Sunday, a league source confirmed to ESPN NFL Insider Adam Schefter.

Suh hit Weeden twice on Sunday. On a video on NFLEvolution.com, one of the league's official websites, vice president of officiating Dean Blandino said he wanted to look into a hit by Suh on Weeden where he lowered his head into the QB while making a hit.

In an NFL Network interview on Wednesday, Blandino explained the fine against Suh.

"We're going to aggressively enforce player safety fouls," Blandino said. "When I looked at the play, I felt that he did make contact with the forehead-hairline. Lowered the head and made contact with the forehead-hairline. Not to the head or neck, but the rule does prohibit that contact to the body."

This is the second time Suh has been fined this season and its the seventh fine of his career, not counting the two-game suspension for stomping on Green Bay guard Evan Dietrich-Smith in 2011.

The fine comes hours after Suh said he felt like he has been under a microscope his entire NFL career.
