The Bolton-born fighter was defeated at odds of just 1/10.
Saturday’s result was great news for bookies as they saw one-way traffic for Khan.
David Williams of Ladbrokes said: “Khan feels robbed but we reckon he’ll get his revenge next year. Peterson remains the underdog but the odds are now much closer.”
Peterson is 11/4 to register back-to-back victories over Khan with the tie at 25/1.
