The latest on the health front for the Celtics-Heat Series opener

Sunday marks the start of the seventh playoff series between the Boston Celtics and Miami Heat since 2010. It was the most common postseason game in the NBA during that span.

As the two sides prepare for a rematch of last year’s Eastern Conference Finals, the Heat are without Jimmy Butler. The six-time All-Star suffered an MCL injury near the end of the first quarter of Wednesday’s 105-104 play-in tournament loss to the Philadelphia 76ers. It happened after a tricky landing on a layup attempt, with Kelly Oubre falling on the affected area.

Butler is expected to be out for several weeks, according to a report from Shams Charania The Athletics. If there is a Game 5 between Boston and Miami, it will be two weeks from when his injury occurred.

Saturday at the Auerbach Center, Joe Mazzulla talked about how the defending Eastern Conference champions are adjusting without Butler.

The visitors are also without Terry Rozier for Sunday’s series opener at TD Garden. The former Celtics guard is dealing with a neck sprain.

Another former Celtic, Josh Richardson, previously underwent season-ending right shoulder surgery, thinning the Heat’s rotation.

Duncan Robinson is questionable for Game 1 due to left facet syndrome. He had eight points in 12 minutes off the bench in Friday’s 112-91 play-in tournament win against the Chicago Bulls.

As for the hosts, Luke Kornet is inactive for Sunday’s match due to a right calf injury.

Sunday afternoon’s game at TD Garden starts at 1:00 EST.
