The 80-player American Century Championship field has been tweaked following the withdrawals of stars.

Joining the Friday through Sunday championship are former boxing world champion Winky Wright, Rascal Flatts’ lead guitarist Joe Don Rooney and 2010 Olympic four-man bobsled gold medalist Steve Holcomb.

Recent departures from the tournament include 1998 champion Mario Lemieux, pro skateboarder Ryan Sheckler, Kansas City Chiefs’ quarterback Matt Cassel, new Notre Dame football coach Brian Kelly and actors Oliver Hudson and Kevin Nealon.
