Cyler Sanderson and Tyler Clark were both granted releases from their scholarships.  Sanderson plans to join his brothers Cael and Cody at Penn State next season. Here's a link to the Des Moines Register story. 

Sanderson, the fourth member of his family to wrestle at Iowa State, will join older brothers Cael and Cody at Penn State. Cael Sanderson is Penn State's head coach and Cody will be an assistant. Cyler Sanderson, an all-American in 2008, will be a senior this winter.

I don't think that Cyler's decision will surprise anybody too much.

Kevin Jackson had this to say about Tyler Clarks deision:

Jackson said the loss of Clark, a two-time qualifier at 125 pounds, is disappointing.

"In our initial conversation I had with him, I didn't get a strong feeling that he felt comfortable with the change," Jackson said. "I think he would have had a tough time making our lineup next year with Andrew Long and Anthony Valles. I think (Clark) saw that as well. I hope the best for Tyler."

Also Jackson said recruits Boaz Beard of Goddard, Kansas and Trent Weatherman of Ballard of Huxley will honor their LOI's to wrestle for ISU next winter.
