Former star gave his blessing for Russell Westbrook to resurrect the No. 0 jersey following his trade to the organization this week.
Arenas, known by the nickname Agent Zero throughout his career because of the uniform number, confirmed on Instagram (via TMZ Sports) he wouldn't object to somebody wearing it for the first time since he left Washington in 2010.
"'0' is all [you] Brodie," Arenas wrote. "It will be a honor."
Westbrook was acquired by the Wizards in a blockbuster deal also highlighted by fellow point guard John Wall heading to the Houston Rockets.
