McKayla Maroney cannot compete at August’s P&G Championships after not entering the last qualifying meet for the event, making it unlikely she’ll return in 2015.

Maroney, the Olympic vault silver medalist who hasn’t competed since 2013, is not in the field for the Secret U.S. Classic on July 25 (full field here). That competition in Hoffman Estates, Ill., will mark the first domestic meet for Gabby Douglas and Aly Raisman since the London 2012 Olympics.

USA Gymnastics confirmed that Maroney cannot petition into the P&G Championships, which are Aug. 13-16 in Indianapolis. She can, however, petition into a later World Championships selection camp. The World Championships are Oct. 23-Nov. 1 in Glasgow, Scotland.

Maroney, the Olympic vault silver medalist, won the World Championships vault title on Oct. 5, 2013 and hasn’t competed since. She missed all of 2014 following knee surgery that March.

A representative from her longtime California gym said Wednesday that Maroney hasn’t been training there due to a slow recovery from that injury.

She also suffered from adrenal fatigue, according to International Gymnast magazine in April.

Maroney said she was unable to get out of bed due to the energy-sapping medical condition.

“Pretty much since 2013, I had burned out everything in my body,” Maroney said, according to the magazine. “With adrenal fatigue, everything in your body is just burned out. It messes up your hormones and goes into things that people don’t understand.”

She took about two months off and returned to training at the beginning of this year, according to the magazine.

“I’ve gotten a lot of IVs that have all these minerals in them,” she said. “I’ve been doing yoga and meditation and everything to heal my body, because I want to go to the next Olympics.”

The fourth member of the five-gymnast 2012 U.S. Olympic champion team — Kyla Ross — is competing at the Secret U.S. Classic along with Douglas and Raisman.

The fifth member, Jordyn Wieber, has retired.

Maroney was adamant in an August interview that she’s determined to make the 2016 Olympic team.

“For people who don’t think I’m, like, really serious about this, you’re wrong,” Maroney said in a USA Gymnastics interview while attending the 2014 Secret Classic. “I want this so bad. I’m not just messing around, chilling, acting. I’ll do that later.”
