Arizona freshman guard Brandon Williams, driving to the basket against Cal Poly forward Mark Crowe last November, will not play this week against the Washington schools. He missed most of the calendar 2017 season with knee problems.

Arizona announced Wednesday that sophomore guard Brandon Williams will miss the season while he continues to rehabilitate his knee injury after another surgery.

Williams has had a congenital issue in his right knee for over three years.

“The news of Brandon’s season-ending surgery is beyond disheartening," UA coach Sean Miller said in a statement. "All of us that comprise Brandon’s Arizona basketball family, as well as our own loyal and passionate fan base, will rally around him and support him as he begins his journey to recovery.”

Williams has suffered since high school with an issue known as osteochondritis dissecans, which sometimes results in bone and cartilage breaking free and causing pain or restricted motion above his right knee.

Williams had swelling on the knee regularly while playing on the EYBL club circuit in 2016, and then had surgery on the knee as a junior at Crespi High School. He stayed out of the game for 10 months, missing the 2017 club season, then eased back and played most of his senior season.

As a freshman at Arizona last season, Williams began having problems with the knee in January.

On Jan. 14 he bruised it in practice and was limited against Baylor the next day, Miller said, while he then reportedly experienced issues after the UA’s game at UCLA on Jan. 26.

Williams missed the next four weeks and, after the season, began rehabilitating the knee again.

He is expected to remain on a basketball scholarship and return, if healthy, to play the 2020-21 season as a redshirt sophomore.

“I want to thank my family, fans and the Arizona Basketball program for their continued support,” Williams said in UA's statement. “I’ve overcome obstacles before in my life and will work with our strength and medical staffs to overcome this one. I’m dedicated to continuing my work in the classroom as a student, and I look forward to supporting my teammates and coaches as I spend this season focusing on my health.”

Without Williams and since-transferred Alex Barcello, Arizona might use grad transfer Max Hazzard as a combo guard who could backup freshman Nico Mannion at point guard when needed.
