Less than two months out from his first scheduled fight in over a year, Keith Thurman doesn’t have an opponent.

And now, it looks there won’t be any need for a foe because the unified welterweight titleholder suffered a left hand injury and won’t fight on May 19 in Brooklyn, New York, as scheduled, according to an ESPN report.

Thurman (28-0, 22 knockouts) suffered the deep bruise in his left hand approximately two weeks ago, per ESPN, and was advised by a doctor to rest his hand for six weeks.

Still, Thurman plans to return this summer. The 29-year-old hasn’t competed since he outpointed Danny Garcia in March 2017, his fourth title defense. He had surgery performed on his right elbow and then travelled to Asia before getting married.

THE RING’s No. 1 welterweight was on the cusp of the pound-for-pound list after the clear victory over Garcia in his most high-profile victory to date. Thurman showed off his boxing ability in the bout, which followed a thrilling decision victory over Shawn Porter in summer 2016.

He possesses the skills and charisma to be a star, but inactivity is beginning to sap any momentum he created. Thurman has competed just twice since a July 2015 victory over Luis Collazo.

Thurman’s return was announced as a split-site telecast during a Showtime press event in January. Adonis Stevenson’s light heavyweight title defense against Badou Jack was scheduled to be paired with Thurman’s return, but for now, only the 175-pound bout will go ahead on Showtime’s May 19 telecast.
