"It's a crazy play. It's one that unfortunately happened," Suh said Wednesday of the play on Thanksgiving Day, adding his kick was unintentional.
"I was being dragged to the ground, and my foot inadvertently hit the man. But it's over with, moving forward and getting ready to play the Colts," Suh said.
Su, in his third season in the NFL, has been fined five times by the league for illegal hits and other offenses.
Including his forfeit of pay in a two-game suspension for stomping the arm of Green Bay Packers offensive lineman Evan Dietrich-Smith last Thanksgiving, Suh has lost $243,000 in income, the Detroit Free Press noted.
Suh admitted the stomp of Dietrich-Smith will likely follow him for the rest of his career.
"I think I'm always going to be punished in some form or fashion for last Thanksgiving. I mean, I apologized for it and I'm going to continue to apologize for it. It's something that happened, a mistake I made," he said.
Suh said he will offer no apology to Schaub for last week's incident in the Lions' 34-31 overtime loss to the Texans.
"A lot of things happen to me. It's part of the game," Suh said.
