No. 1 Buffalo Bills fan Ezra Castro, better known as the masked Pancho Billa, is back in the hospital. And as usual, the Bills family is reaching out.

Castro underwent a CT scan Friday to check on the status of his cancer, which was first diagnosed in the fall of 2018. On his Twitter account, he complained of daily pain and shortness of breath and asked for "positive vibes" while he awaited test results. But later that day, he told his followers that he had been admitted to the hospital because the scan showed something in his lungs that requires further testing.

Castro has received tremendous support from the Bills Mafia and the Bills team as he has undergone treatment.

"Staying #PanchoPower strong & keeping the faith," he wrote in his tweet to followers.
