UFC Hall of Famer and former two-division champion BJ Penn officially announced his return to the Octagon on Tuesday.
Per an interview on The MMA Hour with Ariel Helwani (via MMAFighting's Shaun Al-Shatti), the 37-year-old plans to take another shot at the 145-pound title belt and will work with trainer Greg Jackson.
Penn's last outing in the Octagon was a disappointing loss against Frankie Edgar. His last win came in 2010, when he knocked out Matt Hughes.
