Gibson underwent arthroscopic surgery on his left ankle Tuesday and is slated to miss four months, Marc Spears of Yahoo! Sports reports.

Analysis:

Gibson dealt with the ankle injury late in the regular season, and it appears he may never have been close to full health during the Bulls' playoff run, as he also dealt with shoulder, knee and hamstring issues. The hope is that the procedure will prevent any future ankle problems, but the four-month timetable puts Gibson's status for the start of next season in jeopardy.
