From Yahoo!: “Washington Wizards guard Gilbert Arenas sat out Saturday’s training camp practice with a ‘tweaked’ right ankle while the rest of the team practiced in the dark due to a power outage. Arenas, who also sat out Friday’s practice with leg soreness, was able to play in the team’s scrimmage later that night. ‘Gil went last night, but tweaked his ankle, so he did not go today,’ coach Flip Saunders said.”
