HENDERSON, Nev. -- Less ominous than an agitated and wheelchair-bound Hector Salamanca from "Breaking Bad."
More playful than Pee-Wee Herman doing tricks on his souped-up bike.
The tinny ding-ding of an injured Christian Wilkins hitting the bell on his scooter as he barreled down a hallway to the Las Vegas Raiders locker room earlier this season did more than warn teammates of his impending arrival.
It provided an ironic snapshot of the Raiders' serious and lighthearted-yet-perpetually injured roster.
Indeed, given the rash of injuries to hit the Raiders this season, the busiest people in the building of late may very well be Chris Cortez, the team's head athletic trainer, and whomever is in charge of ordering walking boots.
