"You'll notice that Casey is missing from the group. He is unfortunately sick and in the hospital right now," Ryan Seacrest said when the show began. "Wave to him ... We know you're watching buddy. Feel better - shout out to the nurses. Get back here soon, okay?"

A source told People magazine Friday that Abrams has ulcerative colitis. According to the report, the 20-year-old was treated for the condition, which causes abdominal pain and cramping, at Los Angeles a hospital where he received two blood transfusions Thursday night.

"Hey guys, thanks for the well wishes, I got some nice fresh blood in me and feeling better. People at Idol & Cedars are treatin me real good," he tweeted.

Abrams was also hospitalized in February for severe stomach pains, but was released in time to perform with the season's top 12 men.

His performance of Joe Cocker's "With a Little Help From My Friends" on Wednesday night impressed the judges and was strong enough to move him on to the next round in the competition.
