Sickle cell trait keeps Steelers' safety out of playoff game

Pittsburgh Steelers safety Ryan Clark, one of the team's leading defenders, won't play in Sunday's NFL playoff game in Denver because physical exertion in the city's mile-high altitude may aggravate Clark's sickle cell trait.

"Looking at data and all the variables he is at more risk, so we're not going to play him. It's just that simple," Steelers coach Mike Tomlin said Tuesday, according to CNN affiliate WPXI-TV.

"If he is in any more danger than any of the other 21 men on the field, then we err on the side of caution," Tomlin said at a news conference.

"It is a big game for us, but it is a game," he said.

After a 2007 game in Denver, Clark had his spleen and gall bladder removed and lost 30 pounds from sickle cell complications.

But Clark told ESPN he thought he could play in Denver this weekend despite the risks.

"I talked to my doctors and we actually had a plan in place for me to play. All things pointed to me going until (Tomlin) told me I can't. He said he wouldn't have let his son play and so I'm not playing either," Clark told ESPN.

After hearing that, Clark said he couldn't argue with Tomlin's decision.

"I appreciate coach caring about me more than this football game," he said in the ESPN interview.

The sickle cell trait is an inherited condition that occurs when one parent passes to a sickle cell gene to a child, according to the Centers for Disease Control and Prevention. Those with the trait do not usually exhibit symptoms of sickle cell disease, which occurs when the child inherits the sickle cell gene from both parents.

Sickle cell disease is a blood disorder in which normally round red blood cells, which carry oxygen throughout the body, become crescent- or sickle-shaped. They also become hard and sticky and tend to die early, according to the CDC. And because of their shape, they can become stuck in blood vessels leading to problems including infection and stroke.

But the CDC cautions that those with sickle cell trait can experience complications during both athletic activity and when at high altitudes. Denver, known as the Mile-High City, is 5,280 feet above sea level. Pittsburgh is about 770 feet above sea level.

Clark has been the Steelers' busiest defender this season, according to ESPN.com. He has been on the field for 1,009 snaps this season, or 98.7% of the team's defensive plays. He led the team with 100 tackles.

Clark will be replaced by Ryan Mundy in the starting lineup.

    Man, talk about the ultimate home field advantage. Makes me wish that Paul Brown Stadium was at a higher elevation...

      Not sure what you mean by that. But you seem to be the type of person who would not give anything of value to anyone so STFU. Loser.

    Tomlin for President! He understands teamwork, hard work, organization, and gives a damn about the people involved! Sounds like a perfect candidate or even maybe a VP! Admittedly I am a little crazy, but Tomlin win or lose clearly is a solid human being, from all sides of this, doesn't want to lose a player, doesn't want to incur a cost to the player, team or investors, see the risk and makes the good call.

    Its refreshing to see a coaching staff take a player's health risk in consideration. Tomlin says that he would not let his son play if he had sickle cell trait, and thus he will not let Clark play. That's so awesome. Tomlin is once again proven to be an awesome person and coach. Of course, if this were the Browns, they would have put Clark in and if his liver erupted they would have put him back in (sarcasm in regards to how they handled Colt McCoy's horrific concussion).

    It is not worth risking your life for a game. Someone else can step in and take his place on the field. No one can take his place with his family

    I can't believe people are saying he should play or are calling him weak! My daughter has something similar called spherocytosis. It's also an anemia that causes pre-mature breakdown of the red blood cell. He can actually die if he Hgb drops too low. Educate yourself people!

    Kudos to Tomlin for making the tough call. There seem to be fewer and fewer people involved with pro sports that I can point out to my son as a good role model. Tomlin is one of the few. (But still, GO PACKERS!)

  12. Just do it

    Pittsburgh is actually around 1200 feet above sea level. Try doing some real research Brad!

    Hats off to both the coach and player, I would like to see Clark playing but don't want to see him fall out. For those who call him weak it just shows you have never pushed yourself to your limits and have no concept of what it takes to be a professional athlete or anything for that matter. I grew up old school where you played through pain and at 56 I am paying for that. I am known as being tough but I will tell you it isn't worth the risk. Ask yourself the same thing Tomlinson asked, would you let your son play?

    @ Stanford. Yes, i still say the Steelers are classy. Big Ben was on THIN ice...and he is a STUD QB. He was about one more minor traffic incident away from looking for employment else where. Yes, the Steelers are a class organization. I'm sure Big Ben was smooching up good to management to stay in Pittsburgh. Ray Lewis was found innocent, and deserves an opportunity to play in the NFL. What kind of primadonna league do you want? These guys are not choir boys.
