Rashard Mendenhall on Wednesday posted a blog entry apologizing for and trying to clarify his controversial tweets regarding Osama bin Laden's death.

The Pittsburgh Steelers running back created a stir with comments made on his official Twitter page Monday after news of bin Laden's death broke.

"What kind of person celebrates death?" he wrote. "It's amazing how people can HATE a man they have never even heard speak. We've only heard one side..."

He tried to clarify those comments Wednesday.

"This controversial statement was something I said in response to the amount of joy I saw in the event of a murder. I don't believe that this is an issue of politics or American pride; but one of religion, morality, and human ethics," he wrote.

After quoting a bible verse, he wrote: "I wasn't questioning Bin Laden's evil acts. I believe that he will have to face God for what he has done. I was reflecting on our own hypocrisy. During 9/11 we watched in horror as parts of the world celebrated death on our soil. Earlier this week, parts of the world watched us in horror celebrating a man's death."

He apologized later in the posting and said he was just trying to "generate conversation."

"I apologize for the timing as such a sensitive matter, but it was not meant to do harm," he wrote. "I apologize to anyone I unintentionally harmed with anything that I said, or any hurtful interpretation that was made and put in my name.

"It was only meant to encourage anyone reading it to think."

Rob Lefko of Priority Sports, which represents Mendenhall, confirmed that the running back wrote Wednesday's blog post.

"This was truly, word for word, Rashard's thoughts," Lefko told ESPN.com's James Walker. "It was not written by anyone else and not crafted by anyone else."

Mendenhall on Monday also posted a tweet making a reference to the Sept. 11 attacks.

"We'll never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition style," he tweeted.

Mendenhall has since deleted his 9/11-related tweet. He didn't address the tweet or its deletion in his blog posting Wednesday.

On Tuesday, Steelers president Art Rooney II released a statement regarding Mendenhall's tweets.
