Former world No. 3 Dominic Thiem will once again attempt to restart his comeback next week at the Marbella Challenger.
"It's been a very, very tough period for me and to go back to competition is what I need," he said on social media.
Thiem received a wild card and is set to join a crowded field that includes three-time Grand Slam champion Stanislas Wawrinka, who is also coming back from injury, and ten Top 100 players.
