Ndamukong Suh's teammates call 'Celebrity Diving' show a huge mistake

If you ask Detroit Lions players what they think is funny — 300-pound comedian Louie Anderson in a Speedo, belly-flopping into a pool might pop into their minds.  The thought of their own 6'4", 307-pound defensive end, Ndamukong Suh, leaping off a high dive ... not so much.

Suh should NEVER have signed up to compete on "Celebrity Diving" ... this according to several of Suh's Lions teammates who told TMZ the decision is shockingly irresponsible.

Suh — who's in the middle of a 5-year, $68 million contract with the Lions — recently joined the cast of the ABC reality show.  Suh, who will be joining other celebrities like Anderson, Katherine Webb (Uh, she's everywhere) and former NBA great Kareem Abdul-Jabbar in launching their bodies off a diving platform.

TMZ spoke with several of Suh's teammates who all feel that he's making huge mistake.

"One source told the gossip site, "We need him on the field and if he gets hurt during the off-season doing wild stunts ... it would be bad and it ain't worth it.  He's too valuable to the team."

Another concerned player told TMZ, "If he gets a busted ear drum or an infection, it could have serious effects on his off-season training."

Why the Detroit organization would even allow Suh to take a plunge into the pool had the Lions players scratching their heads.

One source — who happens to be African-American — added, "He's a big dude ... and 'black' and 'pool' don't mix.  He's built for football .. not belly flops."

Tune in for Anderson, endure Webb and stay for Suh.
