The Jazz are awaiting test results to determine the severity of point guard Raul Lopez's potentially devastating knee injury, and it could take even longer before they know how much they can help their unsigned draft pick.
   
"It could be complicated," said David Allred, the team's vice president of public relations.
   
Lopez injured his surgically repaired right knee while playing for his native Spain in an exhibition tournament over the weekend, and doctors for the national team have reported that he tore the same anterior cruciate ligament that he had reconstructed about nine months ago.
