From the visitor’s locker room at Soldier Field on Sunday, Lions center Dominic Raiola tried to put a nothing-to-see-here spin on the seemingly dirty leg stomp he put on Bears rookie defensive tackle Ego Ferguson in the third quarter of the Lions’ 20-14 win.

“I was stumbling through,” Raiola asserted. “And I accidentally stepped on his leg. It was a total accident.”

But the Bears weren’t ready to take Raiola at his word, understandable given the replay of the incident.

“We all saw the play,” Ferguson said. “You can’t take back what happened with that play.”

Added defensive end Jared Allen: “There’s no need for it. That’s our guy’s career here. You can break someone’s ankles (like that).”

The NFL plans to review the incident.

"The matter will be reviewed and appropriate discipline will be applied for any potential safety-related rules violations," NFL spokesman Michael Signora said Monday.

After a 4-yard run by Joique Bell, Ferguson was facedown on the grass when Raiola skipped by and then firmly planted his left cleat into Ferguson’s right ankle. Officials didn’t see the stomp, but the league office will thoroughly review Raiola’s actions for disciplinary purposes.

Ferguson was in pain after the play but returned.

Last month, Raiola drew a $10,000 fine from the league for clubbing Patriots defensive end Zach Moore in the head.

In 2011, Lions teammate Ndamukong Suh was suspended for two games after his stomp on Packers lineman Evan Dietrich-Smith. A suspension for Raiola could prevent him from playing in next week’s NFC North championship showdown in Green Bay.

Another one down: Defensive end Willie Young left Soldier Field in a walking boot with what is likely a season-ending Achilles tendon injury in his left foot.

Young suffered the injury early in the second half and had to be carted to the locker room. It’s doubtful the Bears will push him to play in the season finale at Minnesota, but the severity of Young’s injury will be a big deal.

Coach Marc Trestman wouldn’t say whether Young had ruptured his Achilles. Young will undergo further evaluation Monday.

In good spirits, Young playfully avoided all questions about his injury.

“If it’s on my left side of my body, don’t ask about it,” he said. “(The right side) feels like a million bucks.”

Go fourth and stumble: The Lions prolonged their first touchdown drive with a clutch 21-yard pass to Reggie Bush on fourth-and-6. On the next snap, Bush scored on a 13-yard run.

And when the Bears went for it on fourth-and-goal from the 1 later in the half? The result was an incomplete Jimmy Clausen pass to offensive lineman Eben Britton, plus a pass interference penalty against tight end Martellus Bennett that was declined.

Early penetration by the Lions sent the Bears into scramble mode.

“With the pressure in (Clausen’s) face, it’s just a tough look to go against on that one,” running back Matt Forte said. “Sometimes you wish you could redo it and call a different play.”

Extra points: Guard Kyle Long missed the first game of his career because of a hip injury. Also among the Bears’ inactives were kicker Robbie Gould (quadriceps) and safety Chris Conte (back). ... Lions receiver Calvin Johnson had 103 yards on six catches, his fourth 100-yard game against the Bears and second this season.
