Kristaps Porzingis

With his three blocked shots on Thursday, Porzingis has recorded multiple rejections in four of his last five outings. The biggest concern remains availability, as the Celtics big man is working his way back from offseason left leg surgery and has recently dealt with a sore right heel. The good news for fantasy managers is that Porzingis and the Celtics won't play a back-to-back until January 1-2, so he should be able to get in a good run of games.

Porzingis (heel) is available for Thursday's game against the Bulls, Justin Turpin of WEEI.com reports.

Porzingis is back in action after logging just 11 minutes in his last outing. He practiced ahead of Thursday and Boston is comfortable with him testing things out. It's unclear whether he'll handle his usual workload, though.

Tillman's absence will not significantly impact the Celtics' rotation or fantasy basketball, as the team's other bigs are available to play. Al Horford, Luke Kornet, and Neemias Questa are all available to supplement Kristaps Porzingis.

Porzingis (heel) is questionable for Thursday's game against the Bulls, Taylor Snow of the Celtics' official site reports.
