If the 2019-20 NBA season resumes and the Warriors play more games, Kevon Looney will not be taking the floor.
Looney underwent surgery Tuesday to repair a core muscle injury, the team announced Wednesday afternoon.
The procedure was performed by Dr. William Meyers at Vincera Institute in Philadelphia.

The 24-year-old is expected to be ready for the beginning of the 2020-21 season, which might not begin until late December because of the coronavirus pandemic.
Looney's season basically was derailed before it even started. He tweaked his hamstring a couple of weeks before training camp opened, aggravated the injury Oct. 2 during the Warriors' second practice and missed all five preseason games.

He returned for the season opener vs. the Los Angeles Clippers, and grabbed nine rebounds (five offensive) and hit a corner 3-pointer in just 10 first-half minutes. But, he did not return for the second half and missed the next 20 games to deal with a neuropathic issue.

"It's been kind of frustrating," Looney told NBC Sports Bay Area's Logan Murdock in late December. "Being hurt."
"You just kind of deal with it," he said. "Manage it. Do what you can do, but when it hit my hamstring, it was something I couldn't control and something I couldn't play through."

After returning to the lineup Dec. 2, he was sidelined for 18 games from Christmas Day through the end of January because of an abdominal strain.
Looney appeared in 10 of Golden State's 11 games in February, but missed the first three games in March. And prior to the Warriors' matchup vs. the Philadelphia 76ers on March 7, the team announced Looney would miss at least the next three weeks because of ongoing left hip soreness.
Warriors coach Steve Kerr repeatedly has referred to Looney -- who signed a three-year, $15 million contract extension last summer -- as a "foundational piece."
The No. 30 overall pick in the 2015 NBA Draft underwent surgery on his right hip in August 2015, and then had surgery on his left hip in April 2016.
