The Chiefs opened a three-day rookie camp today by signing two draft picks, center Eric Kush and linebacker Mike Catapano. Kush, from California University of Pennsylvania, was a sixth-round pick while Capapano, from Princeton, was a seventh-round selection.

Six of their eight draft picks remained unsigned, including tackle Eric Fisher, the first overall pick.

In addition to their eight draft picks and 13 undrafted rookies, the Chiefs were expecting 44 other players to participate in rookie camp. Eight are first-year players under contract to the Chiefs: wide receivers Junior Hemingway and Tyler Shoemaker, tight end Kevin Brock, offensive linemen Steven Baker, Tommie Draheim, Dustin Waldron and Lucas Patterson and linebacker Chad Kilgore.

The others are players invited to camp without a contract on a trial basis. Among the names that are locally familiar: kickers Anthony Cantele of Kansas State, and Trey Barrow of Missouri and quarterback Dayne Crist and linebacker Toben Opurnum of Kansas.
