Center Sean Marks has signed with the San Antonio Spurs after two injury-riddled seasons with the Heat, agent Marc Fleisher said Friday.

Marks, a member of the New Zealand national team that finished fourth at the 2002 World Championships, was limited to 44 games in his two seasons under Pat Riley.

The 6-foot-10 outside shooter faces long odds with the Spurs, with Tim Duncan, Rasho Nesterovic, Malik Rose, Kevin Willis and Robert Horry already in place in San Antonio's power rotation.

Fleisher, who also represents Heat free-agent center Vladimir Stepania, said Stepania has yet to reach a free-agent agreement. Fleisher said there has not been contact with the Heat regarding Stepania since Wednesday.
