Andy Roddick has withdrawn from a World Team Tennis match in St. Louis, citing a lingering injury.

Roddick was scheduled to play Saturday for the St. Louis Aces in a match against Kansas City. Aces general manager Dani Apted says Roddick’s injury is too severe for him to play or travel to St. Louis.

In a statement, Roddick said he’s been dealing with the injury since mid-May. He did not specify the injury.

“I love World Team Tennis and Billie Jean and I’m so sorry that I will be unable to be in St. Louis on Saturday night. Due to the same injury that I’ve been rehabbing since mid May, I’m seeing a specialist and have been advised not to travel. I want to wish my teammates good luck and hope they get a win!”
