Matt Pobereyko, a pitcher who played under various minor-league baseball teams throughout his career, is dead. He was 31.

“He just dropped, and that’s all we know,” he added. “We don’t know. There’s nothing outstanding on the autopsy. But from what I understand, he would have gotten a clean bill of health if he had a pulse.”

Pobereyko’s brother said his death came as a shock this his family.

“For what we know now, there’s really no leads,” he shared. “They saw him earlier in the week, and he seemed to be perfectly fine.”

The baseball player was found “unresponsive on his kitchen floor” and “pronounced dead on the scene,” Warrenville Police Chief Sam Bonillaconfirmed to NBC News, adding that “there were no suspicious circumstances to report, and an autopsy conducted the following day did not reveal anything further.”

The Warrenville Police Department did not immediately respond to PEOPLE’s request for comment.

His cause of death is “pending further investigation,” a spokesman for the DuPage County Coroner’s Office told the outlet and projects that it will take almost eight weeks for the cause to be determined.
