LSU's live mascot Mike Tiger VI has developed a dark patch on his face following radiation therapy he underwent for a spindle cell sarcoma.

An LSU spokesperson said the noticeable dark spot around the 420-pound tiger's right eye, which was previously covered by fur, formed naturally from his skin's melanin to protect the area from sunlight.

Mike was diagnosed with spindle cell sarcoma on the right side of his face in May after caretakers noticed swelling round his eye.
