On the bright side, Followill is expected to make a full recovery. Yesterday the band posted an optimistic YouTube clip of Followill in his hospital bed, talking about his recovery. "I'm going to get completely healed up and get out there," he says in the video.

He also apologized to fans for their canceled shows in New York, Virginia, Ohio, Indiana and New Hampshire, saying, "Sorry I had to skip out on these few shows but it's all for the better. Thanks for all the well wishes. I'll see you guys on the next show."

That would be when they play Holmdel, N.J., on Aug. 28. However, the band were still scheduled to make their appearance on last night's episode of The Tonight Show With Jimmy Fallon. Followill was replaced during the TV taping with The Roots' Questlove.
