Jason Quick of the Oregonian reports (via blog):

Trail Blazers guard Jerryd Bayless sprained his left ankle about an hour before tip off of Saturday’s game in Charlotte as he was returning to the locker room.

Bayless rolled his ankle on a disguised step that is hidden by carpet. The six-inch drop off is in a dimly lit area just outside the tunnel that leads from the court to the Blazers locker room.

Bayless was carried by Rudy Fernandez and Dante Cunningham the remaining 20 yards to the Blazers’ training room, where he was despondent on the training table.
