Collins missed his second straight game because of symptoms related to a concussion he suffered on Memorial Day. Collins was undergoing tests Wednesday and his next on-court activity is scheduled for Friday's practice.
Associate head coach Michael Curry coached in Collins' absence.
"It was all scripted by him," Curry said of Collins.
Kapono said it was not quite the same without Collins patrolling the sideline.
"First off, we hope coach is going to be OK," Kapono said. "Coach is always into every detail in practice. He's been calling and texting, so he has been involved. We didn't know he was not feeling well. We hope he gets back as soon as possible."
