Croatians Ivo Karlovic and Mario Ancic have been added to the sideline list for the US Open. Both players have withdrawn from the tournament due to injuries.
Karlovic had surgery on his left Achilles’ tendon since the Madrid Masters in May and has not played since then. Ancic is currently suffering from a back injury.
Jamaica’s Dustin Brown and Germany’s Tobias Kamke will take over their positions.
