Gay (ankle) is doubtful for Sunday's game against Boston, Jason Jones of The Sacramento Bee reports.

EDGE Analysis

Gay left Friday's game early in the first quarter with a sprained left ankle and did not return to action. He was initially considered day-to-day, but has since been downgraded to doubtful in advance of Sunday's matchup with the Celtics. Omri Casspi is the likeliest candidate to step into the starting lineup should Gay miss Sunday's contest.
