Ryan Carnes will take over the role as Lucas Jones on "General Hospital" this summer, reports TV Guide Online. Lucas is the son of Bobbie Jones (Jacklyn Zeman). The daytime newcomer replaces actor C.J. Thomason, the most recent Lucas from 2002-2003. This move is a part of a usually growing summer teen storyline. No word yet on whether the role is contract, though it is likely to be recurring.
