On this day: IT goes for 38 vs. Rockets; Celtics hold Knicks to 46 points

On this day in Celtics history, Isaiah Thomas goes off for 38 points against Houston, and Boston holds New York to just 46 points.

On this day in Boston Celtics history, the storied franchise set a record for the ages by holding their opponent on the night to the fourth-lowest score in their ball club’s seven-plus decades of existence.

That record would be set in the ball club’s very first season of existence (1946-47) — incidentally, also the first season of the Basketball Association of America (BAA, a precursor league to the NBA). The game was played just two days after Boston set a record for the second-lowest score an opponent was held to in franchise history, a 48-43 win over the (now defunct) Pittsburgh Ironmen.

The Celtics nearly duplicated the feat in a 52-46 win over the New York Knicks on Jan. 25, 1947.
