The Miami Herald (Michael Wallace) reports:  Heat forward Shawn Marion was knocked out of Wednesday’s practice because of an eye injury and is questionable for Thursday’s game at Chicago. Marion was injured late in the workout, when forward Michael Beasley inadvertently hit him in the left eye during a drill. Marion was taken to a doctor for treatment and diagnosed with a bruised left eye orbit. Marion, the Heat’s leading rebounder, traveled with the team Wednesday and will be evaluated Thursday.
