HOUSTON — Le’Veon Bell set a Steelers postseason rushing record twice within eight days in January while playing with an injured groin that may now need surgery.

If so, it would be the second consecutive time he will have had surgery after his season ended with an injury, and the NFL is investigating why coach Mike Tomlin did not put him on the team’s official injury list before those games.

Bell, making the rounds of Super Bowl media interviews while representing FedEx on Wednesday, told the Post-Gazette that one doctor advised him to have surgery and a second told him his injured groin would heal with rest.

“I’m going to see a third,” Bell said, and that surgery is “definitely” possible.

Bell said his groin was hurt when he was tackled during the Steelers playoff victory against Miami at Heinz Field Jan. 8, when he set the Steelers postseason rushing record with 167 yards. He broke that the following week with 170 yards against Kansas City.

However, he came out of the AFC championship game against New England in the first quarter after just five carries when his groin injury flared up. He went back for one more carry but left the field for good when he realized he had no burst.
