The Runnin' Rebels (29-6) face No. 2 seeded Wisconsin (30-5) on Sunday morning (11:30 a.m. PST) in the second round of the Midwest Regional at the United Center here.
White, who scored 19 points and grabbed a team-high eight rebounds against the Yellow Jackets, had the injury X-rayed after the game and no ribs were found to have been broken.
"Yesterday it felt like it was broken," White said. "It really did. I was so happy when they told me it wasn't broken."
White took part in UNLV's 90-minute closed practice at the United Center on Saturday morning and said he still felt some pain in the area.
"When I extended (his arms up), like when I shoot, it kind of hurt," White said.
The first team all-Mountain West Conference pick said he wasn't sure if he would wear any special padding to protect the area. But he was adamant that he would not get any kind of injection to help fight the pain.
"I don't think I can take one," White said. "I've had too many shots this year. I'm scared of the needle right now. I really am."
