Tyus Jones played three games with back spasms and was forced to sit out a fourth as his high school team, Apple Valley of Minnesota, rallied for a 73-64 victory on Wednesday.
"I don't know when he will be back," Apple Valley coach Zach Goring said. "I'm not going to bring him back now until he's 100 percent healthy."
Jones, the nation's top-ranked recruit in the class of 2014, hasn't practiced since Dec. 11.
"It's [gradually] been getting worse," Goring said. "We need to get him back to normal, and decided let's just rest him now."
Despite his back issues, Jones averaged 29.7 points in Apple Valley's first three games.
"He has been doing everything he can to take care of it," Goring said. "He has been putting heat on his back, icing it, stretching and going to the chiropractor."
