The Celtics say All-Star point guard Kemba Walker is probable to face the Brooklyn Nets on Wednesday (7 p.m. ET, ESPN) in Boston.
Walker was hospitalized after suffering a neck sprain Friday when he collided with teammate Semi Ojeleye during a game against the Nuggets in Denver.
He did not play in Monday's win over the Sacramento Kings.
Daniel Theis (ill) remains questionable to face the Nets, who won't have Kyrie Irving and are listing DeAndre Jordan (sore ankle) as questionable.
