BATON ROUGE, La. — Cancer found in the skull of Louisiana State University’s live tiger mascot has spread.

The LSU School of Veterinary Medicine announced that a CT scan and physical exam of the tiger, Mike VI, shows the tumor in his skull has grown and his cancer has spread. The school scheduled a press briefing Wednesday to discuss the tiger’s prognosis.

LSU announced in May that the tiger had been diagnosed with a rare and inoperable form of cancer. At the time, veterinarians said treating its spindle cell sarcoma with radiation therapy could extend the 10-year-old tiger’s life by one or two more years.

Last month, LSU announced that Mike VI won’t take the field during home football games this season, and instead will remain in its campus habitat.
