Mavs officially sign Ferrell to multi-year deal

DALLAS - The Mavericks have signed rookie point guard Yogi Ferrell to a multi-year deal after a dazzling start under a 10-day contract.

The agreement announced Tuesday comes after Ferrell averaged 17.2 points and five assists in five games, all starts. That included a 32-point game and a critical 3-pointer at Portland when Dallas won a season-best fourth straight game.

Ferrell tied an NBA rookie record with nine 3-pointers in the 108-104 victory over the Trail Blazers on Friday. He was undrafted out of Indiana, the alma mater of Mavericks owner Mark Cuban. The 23-year-old played 10 games with Brooklyn earlier this season.

The Mavericks signed Ferrell after Pierre Jackson, another guard on a 10-day deal, injured a hamstring. Starting point guard Deron Williams has missed the past six games with a left big toe sprain.
