Frequently decried as a cheap-shotting menace on the field and a reckless driver off of it, Ndamukong Suh could use a bit of positive PR. Saving the life of a fellow celebrity could be just that. Does it count if that celebrity is Louie Anderson? I suppose that’s for the public to decide.

Comedian Louie Anderson narrowly averted disaster this week at a taping of “Splash” — because he nearly sank to the bottom of the pool from sheer exhaustion — but thankfully, Detroit Lions star Ndamukong Suh came to the rescue.

Sources close to the production tell TMZ, Louie — who’s a contestant on the show — was practicing his dives on Wednesday when he became a little too bushed to pull himself up the ladder … falling back into the water again and again.

We’re told Louie eventually had to be rescued by Suh and divemaster Greg Louganis — who physically lifted the foundering funnyman to the poolside. Louie then sat coughing up water for several seconds.

Cheers to Suh. I believe this act entitles him to three more kicks to a quarterback’s nuts, free of media outcry. Provided it’s not a quarterback the media really likes, like Rodgers, Brady or a Manning.
