Singing soldier Timothy Michael Poe, who was known more for his questionable sob story about being injured in Afghanistan than his singing on America's Got Talent, was cut from the popular NBC show last night.

So-called singing soldier Timothy Michael Poe claimed a grenade attack in Afghanistan caused him to suffer a traumatic brain injury, which in turn led him to acquire a stutter, although his story about the grenade could not be confirmed by the Minnesota National Guard.

Timothy Michael Poe sang George Strait's The Chair last night on the Las Vegas episode. His singing did not wow over judges Howard Stern, Sharon Osbourne and Howie Mandel.

I don't know that he holds up to other singers on this show at all, Mandel said during last night's episode of America's Got Talent, the Associated Press reported.

The episode aired before the controversy surrounding Poe started, the AP reported.

Poe told a Dallas television station that he believed he was telling the truth, according to the AP. Part of the controversy was stoked after Poe sent a photo of another soldier he claimed was himself to America's Got Talent. Poe's fiancée said the photo was submitted in error because the crooner was rushed, the AP reported.

Poe's run on America's Got Talent was among the most popular when he recounted his story about why he stuttered during his audition. The 35-year-old Poe, of San Antonio, Tex., said he didn't even know he had a knack for singing until he was sent to a speech pathologist due to his alleged brain injury.

I didn't know I could really sing until my speech pathologist told me that to help my stutter, she said to sing in the shower, Poe told the America's Got Talent judges.

In a pre-taped video that aired on the show, Poe recounted his tale of being hit by the grenade, which the Minnesota National Guard could not confirm.

I saw it coming down and by the time I turned and went to jump on top of my guys, I yell, 'Grenade!,' and the blast had hit me, Poe said, noting that he thought his life was over.

When I was lying there, I thought that I was never going to be able to see my daughter walk down the aisle or throw the baseball with my son again or be able to hold them and see them. I didn't want my life to be over, 'cause there's so much to do that I would never be able to do.

A day after Poe's performance, the Minnesota National Guard said the aspiring country singer's military records do not indicate that he was injured by a grenade in combat while serving in Afghanistan in 2009, as he reports.

Katy Edwards, who says her sister has a child with Timothy Michael Poe, also said the aspiring country singer's story was made up.

He never actually fought in Afghanistan. He did break his back but it was in Georgia when he was in training to go on a deployment. On this particular deployment he landed in Afghanistan, got an ear infection and was medevac'd out to Germany, Edwards said in an e-mail to IBTimes. While in Germany he refused to go back to the war and was brought back to the United States. His unit lost a soldier that deployment and are incredibly upset by the stories he made up [Monday] night.

Edwards said she was appalled that Poe would fabricate such a story on national television.

What he did last night was a slap in the face to all our great servicemen and women, she said. The most disgusting fact of all is that Tim doesn't even have a stutter. My sister has a child with him. I have personally spoken with him several times in the last year and he is completely healthy and fine.

Poe served in the Minnesota National Guard as a supply specialist from December 2002 through May 2011, according to records obtained by the Associated Press. He served in Kosovo in 2007 and 2008 and served in Afghanistan for a brief period in 2009.
