A spokeswoman for the Penza governor's office said self-styled prophet Pyotr Kuznetsov was in a serious condition in a hospital in the town of Bekovo, near the site where 11 of his followers were still holed up in their bunker.
Both the spokeswoman and the hospital declined to say what caused his injuries. He has been undergoing court-ordered psychiatric treatment.
Late Wednesday, Deputy Governor Oleg Melnichenko said in televised comments that Kuznetsov was hospitalized with a self-inflicted open head wound.
"It was a suicide attempt," Melnichenko said on NTV television. He said Kuznetsov had laid his head on a tree stump and hit himself repeatedly on the head with a piece of wood.
Earlier, Interfax had cited Melnichenko as saying cult members had beaten Kuznetsov during an argument. There was no explanation for the discrepancy.
Some 35 Kuznetsov's followers barricaded themselves in a bunker beneath a field in October in anticipation of the end of the world, which they said would come in April or May. But over the past week, 24 people have come out, mainly because they say rain has caused the structure to start caving in.

A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
