The development is punishment for various offseason issues.
Henderson was suspended in July after reportedly failing multiple drug tests.
“I want to thank coach [Andy] Kennedy, [athletic director] Ross Bjork and the university for giving me an opportunity to rejoin the team,” Henderson said in a statement. “This has been a difficult time for me, and I appreciate this chance. My teammates and I are looking forward to defending our SEC Championship.”
