Mavericks Trade Guard Josh Richardson to Boston Celtics

After a quiet draft night Thursday, the Mavs appear to be starting off their offseason moves. Dallas reached an agreement Friday to trade guard Josh Richardson to the Boston Celtics, a source confirmed to the Dallas Morning News's Brad Townsend. The news was initially reported by Shams Charania of The Athletic.

Richardson will exercise his $11.6 million player option to facilitate the deal. The move gives the Mavs the ability to have up to $34.3 million in salary cap space, but only if Dallas doesn’t re-sign free agent Tim Hardaway.

Can confirm @ShamsCharania report of Josh Richardson trade to Celtics, though trade won't be completed until Saturday for bookkeeping purposes. Deal gives Mavs ability to have up to $34.3 million in cap space, but that figure only would be reached if Hardaway signs elsewhere.

The Mavs acquired Richardson last summer in a trade with the 76ers that sent Seth Curry to Philadelphia and brought Richardson and Tyler Bey to Dallas.
