Celtics big man on track to return for Game 1 of NBA Finals

Celtics big man Kristaps Porzingis, who has been on the shelf for over a month due to a calf strain, is on track to return to action in Game 1 of the NBA Finals, assuming he doesn’t experience a setback before Thursday’s tip-off, sources tell Shams Charania of The Athletic.

Porzingis was injured during Game 4 of the Celtics’ first-round series against Miami on April 29. He was diagnosed with a strained right soleus and a muscle in the calf and missed the entire Eastern Conference semifinals against Cleveland and the conference finals against Indiana.

However, Porzingis has been ramping up his activity in recent weeks in the hopes of returning for the NBA Finals. According to Charania, the 28-year-old has participated in multiple scrimmages within the last few days.

“Monday was a very, very critical day for Kristaps Porzingis and the Celtics,” Charania said during an appearance on FanDuel’s Run it Back show. “He completed a second 5-on-5 scrimmage in three days. It was a success, he came out well.”

It’s unclear whether Porzingis will immediately reclaim his spot in the starting lineup once he’s cleared to return — or what sort of minutes limit he might face. During his absence, reserve center Al Horford has started Boston’s past 10 games, with Luke Kornet, Oshae Brissett, and Xavier Tillman all seeing some minutes off the bench at the five.

A healthy Porzingis would provide rim protection on defense and add one more dimension to the Celtics’ offensive attack. In his three full playoff games, before he was injured, he averaged 14.0 points, 5.7 rebounds, 2.3 assists, 2.0 blocks, and 1.7 steals per game on .419/.412/.900 shooting.
