Sims exited Wednesday's 117-94 preseason win over the Wizards after sustaining a sprained ankle, Kristian Winfield of the New York Daily News reports.
Sims' night was over right after it started, as he suffered the injury in his second minute of play. The center didn't record any counting stats. The severity of the sprain is unclear, but his next chance to play will come Sunday against the Timberwolves.
