U.S. authorities in California say former Edmonton Oilers owner Peter Pocklington will serve three extra months of federal probation in a 2010 perjury case.
Assistant U.S. Attorney Antoine Raphael said Thursday the probation was to end Oct. 26 but was extended at a hearing in a Riverside federal court Wednesday.
Raphael says authorities are looking into whether Pocklington may have withheld personal financial information from probation officials.
Prosecutors will use the extra months to determine if there was wrongdoing.
Pocklington's attorney, Brent Romney, did not return messages seeking comment.
Pocklington pleaded guilty to perjury in May 2010 after prosecutors alleged he concealed assets during bankruptcy proceedings.
The Oilers won five Stanley Cups under Pocklington's ownership, but he stunned fans by trading Wayne Gretzky to the Los Angeles Kings in 1988.
