Two people with knowledge of the deal say the Dallas Mavericks are acquiring Caleb Martin in a trade with Philadelphia that sends Quentin Grimes to the 76ers.

Martin came to the Sixers with huge expectations but was plagued by injuries. He missed the last 12 games. KJ Martin, another Sixers forward, was sidelined Tuesday because of a pending trade.

The Philadelphia 76ers announce the trade of Quentin Grimes is official while also revealing what uniform number he will wear.
