A week after being admitted to a San Antonio hospital for complications relating to his long-term struggle with Crohn's disease, Riot guitarist Mark Reale remains in a coma -- but although he's in critical condition, the latest news update from his official site maintains a positive outlook while leaving fans the ability to send personal prayers and messages to Reale's bedside.

"Mark had a Subarachnoid Hemorrhage and that is why he's still in a coma since Jan. 11, 2012 when he was rushed to the hospital," reads the update. "Mark is also fighting several other critical conditions, but is getting the very best care here in San Antonio from gifted and talented doctors. Please continue to keep Mark in your thoughts and prayers, I continue every day reading them to Mark! God hears all of us, ask for HIS goodness to heal Mark."

Reale formed Riot in 1975 and the band has enjoyed a successful career to this day, sharing the stage with everybody from AC/DC and Black Sabbath to Sammy Hagar and Kiss.

Riot is currently touring behind its latest album, 'Immortal Soul,' and played its first show without Reale on Wednesday in New York. The band addressed Reale's condition in an update at its site, saying, "While we are saddened by these developments, Riot's music has been Mark's lifeblood for over 30 years. We have struggled with idea of performing without him, and we are continuing to prepare with heavy hearts, but the entire Riot organization has agreed on the importance of bringing our music to the fans who have supported us for so long."
