Rehabbing from his latest wrist surgery, Juan Martin del Potro will aim to reconstruct his support team.

The 2009 U.S. Open champion announced he has split with long-time coach Franco Davin and trainer Martiniano Orazi.

"I wanted to tell you that Franco and Martiniano are no longer part of my team," del Potro wrote in a Facebook post. "I'm really grateful for the years we've worked together and I wish them the very best. I'm also thankful to their families for their warm support that goes beyond tennis."

The 26-year-old Argentine has not yet announced replacements to his team.

Injury-induced inactivity has caused the former world No. 4's ranking to drop to No. 569.
