DALLAS (AP) A person with knowledge of the deal says the Mavericks and Dirk Nowitzki have reached agreement on a two-year contract that could get the star forward to 20 seasons in Dallas.

The agreement would be worth roughly $20 million per season with a player option in the second year, the person told The Associated Press on Tuesday on condition of anonymity because contracts can't be signed until late Wednesday night Central time.

The person also said the Mavericks have agreed to a two-year, $6 million contract with free agent guard Seth Curry, the younger brother of two-time MVP Stephen Curry.
