ESPN's Shams Charania reported Wednesday that the Celtics "don't quite know" when Kristaps Porzingis will return from a viral illness.

Thunder head coach Mark Daigneault said the Celtics are a “significantly” different team when Porzingis is not available — no other Boston big can replicate his combination of 3-point shooting and top-tier rim defense — but still a formidable foe because of their depth and versatility.

Big man Kristaps Porzingis has missed each of the Boston Celtics ' last seven games due to an illness. In those games, the Celtics are 5-2. However, it is clear that they would much rather have the Latvian native healthy and available to play.
