Checking out his twitter tonight, Clark was thanking his fans for buying his jersey. He also mentioned that if Mewelde Moore retires or doesn't return to the Steelers, he wants to try and change his number 21. In memory of course of his long time friend, Sean Taylor, tragically shot and killed in his home on November 27, 2007.

For everyone who bought my jersey thank you! If Mewelde Moore doesn't come back I will attempt to change my # to 21. We'll see.
