Suge Knight was famously at the wheel of the car Tupac was in when a drive-by shooter ended the legendary emcee.

One of the bullets intended for Pac grazed Knight's head and left behind a fragment.

Knight has been having health issues lately, passing out in court and apparently going blind. Doctors want to scan his brain to see what's going on but the bullet fragment has been getting in the way of their imaging.

The docs want the bullet removed, but Knight won't let them.

His refusal to go under the knife has nothing to do with sentimentality. Instead, the 50 year old believes that such a surgery in his weakened state would kill him.
