The Voice's Hannah Goebel missed her Battle against Alexa Cappelli due to personal reasons, and now the artist is explaining her absence.

On behalf of coach Kelly Clarkson's team, Hannah, a 21-year-old musician from Nashville, TN, was paired with Alexa, an 18-year-old from Upland, CA, to sing "Pray" by Sam Smith for their Battle, which aired on Tuesday night's episode of The Voice.

However, show host Carson Daly announced before the Battle that Hannah "had to leave" for "personal reasons," allowing Alexa to sing their song alone and then automatically advance to The Voice's Season 14 Knockout Round.

"Hey everyone! I want to start off this post by giving my utmost thanks to the @nbcthevoice team, coaches, fellow contestants, fans and friends who provided me with an incredible level of support throughout this entire process," Hannah captioned a photo of herself on Instagram.

"As many of you have now heard, I left this season of The Voice due to personal reasons. I want to assure everyone that I am well; I still have my voice and am looking forward to a long music career and recording original songs in the near future."

While Hannah did not disclose the exact reason for her departure, she seems to be in good health.

Hannah's exit appears to have been last minute, as she recorded the "Pray" single in the studio with Alexa and the song is currently available on iTunes. In addition, NBC's press materials for the show include photos showing Hannah and Alexa meeting with Kelly and her team advisor Hailee Steinfeld to discuss their performance.

As shown on Tuesday night's pre-taped episode, Alexa performed "Pray" alone onstage for the studio audience and advanced to the next round by default.

Alexa's performance aired as a brief clip within a montage that also featured two other Battle performances, so most of the coaches' comments were not shown.

If Hannah had stayed in the competition, she had an excellent chance of surviving the Battle Round.

Not only did the talented artist's Blind Audition of "If I Ain't Got You" earn her a four-chair turn, but Kelly also used her one "Block" of the season to prevent Hannah from joining Alicia Keys' team. Blake also insisted he'd "go down bleeding" to have Hannah on his team.
