PHILADELPHIA (CBS) —  If you were hoping to get a glimpse of her in person in the boxing ring tonight, you’re out of luck!

Patricia Krentcil- whose overly-tanned skin caught the eye of police, putting her in the national media spotlight- has backed out of a scheduled boxing match in Essington at the last-minute.

According to her official Twitter page, Krentcil cancelled because she hurt her back.

Krentcil was set to fight transgender radio personality Kayla Vas at the Wyndham Garden Hotel.

She does say she’s still planning to donate, presumably to the Brain Tumor Awareness charity that’s been advertised in promotions for the event.

Krentcil has posted several tweets in the past day or so, saying that she’s very sick.

Krentcil was accused of taking her 5-year-old tanning with her in 2012.

The charges were eventually dropped.

She has since made the rounds on the celebrity boxing circuit.
