 Gymnastike reports that new daddy, Jonathan, is recovering from shoulder surgery last year and he is not quite competition ready yet.
Since 2002, Jonathan has been on the roster for every single national championships roster. His olympic teammates, Danell Leyva, John Orozco, Sam Mikulak and Jake Dalton will still compete in Hartford this weekend.

Replacing Jonathan is Steve Jaciuk from New Berlin, Wisconsin. Steve attends the University of Minnesota where he will be headed into his junior year this fall. Here is his bio on the University of Minnestota's Gopher Sports Guide
