Dallas Mavericks rookie Cooper Flagg (left midfoot sprain) is listed out for Tuesday’s game against the Brooklyn Nets.

AND ...

Due to the East Coast weather, no 'Tonight Show' guest spot tonight, either.

From our Grant Afseth: 

A major New York City blizzard has postponed Cooper Flagg’s Feb. 23 appearance on The Tonight Show Starring Jimmy Fallon after travel into NYC was halted, with 5,000+ U.S. flights canceled.

The Mavs will remain in Indiana overnight on Monday.
