"American Idol" finalist Phillip Phillips is slated to undergo kidney surgery, following Wednesday's finale.

In March, Phillips was rushed to the hospital with severe abdominal pain and he was ordered by doctors to undergo "immediate" surgery, but it was reportedly put off in order for him to compete in the reality singing competition series.

Phillips, a 21-year-old Georgia musician, and Jessica Sanchez, a 16-year-old power vocalist from San Diego, California, were on Thursday named the final 2 contestants on the current 11th season of "American Idol" following the elimination of 20-year-old Joshua Ledet of Louisiana.

According to the Hollywood Reporter, Phillips refused treatment when he went home to Leesburg, Georgia, in an effort to keep up with the show's schedule. Phillips, who according to a show insider, is in severe pain and was excused from the weekly Ford video shoots.

According to Us magazine, the ailment has affected Phillips' ability to sing and he has undergone five kidney stone removal procedures since October 2011.

On Wednesday, Phillips had performed an acoustic version of "Disease," from Matchbox Twenty's 2002 album "More Than You Think You Are." The original track has a hard rock sound. Jackson said he didn't like Phillips' rendition, calling it too "subdued." Co-judges Jennifer Lopez and Steven Tyler were also not that enthusiastic about it.

Phillips has emerged as the token season heartthrob and his voice has been compared to Dave Matthews'. The latter singer's band has a similar fan base to Matchbox Twenty, which is also known for songs such as "Push," "Real World," "Bent" and "If You're Gone."

On Wednesday's episode, all three judges praised Phillips excitedly for his other two performances, namely his soulful rendition of Bob Seger's 1978 ballad "We've Got Tonight."

The winner of "American Idol" will be announced on May 23 on FOX.
