ALLEN PARK, Mich. -- Detroit Lions coach Jim Schwartz defended Ndamukong Suh on Monday from a report that the defensive lineman had issues controlling his personal fouls in practice.

“I can say unequivocally, he has never slammed anybody’s head to the ground or stomped on anybody [in practice],” Schwartz said Monday. “That’s just inflammatory stuff that it gets headlines and gets reaction.

“But I would bet that you guys would have reported that long before a guy who has never been to one of our practices.”

According to multiple reports, Jay Glazer said on Fox that “you talk to people inside Detroit and they say even in practice, Ndamukong gives guys the business. He’ll slam a guy’s head against the ground, he’ll take little shots at guys, and guys are concerned that if he can’t control himself even in practice, how can he control himself against somebody else’s jersey.”

Suh has a history of personal foul fines from games, including last week when he was docked $100,000 for a low block on Minnesota center John Sullivan. He had also been previously fined for personal fouls and unnecessary roughness on quarterbacks Jay Cutler, Jake Delhomme, Matt Schaub and Andy Dalton.

He was also suspended for two games for stomping on Green Bay Packers lineman Evan Dietrich-Smith in 2011.

Schwartz was adamant nothing of the sort has happened in practice with Suh.

“Unequivocally, I think that’s off base,” Schwartz said. “He’s done a very good job of, in practice, working around the quarterback. He had one time in all of training camp that he ended up in a power rush and put a lineman back into a quarterback, which is something we try to avoid as best as we can.

“But he had one and that’s probably the least amount of all our defensive linemen.”
