Milwaukee Bucks forward Bobby Portis is declining his $3.8 million player option and will become a free agent, agent Mark Bartelstein told ESPN's Adrian Wojnarowski on Saturday.

The most the Bucks can offer Portis is a $5.9 million exception, according to ESPN's Bobby Marks.

The 26-year-old Portis was one of the more effective sixth men in the NBA, averaging 11.4 points and 7.1 rebounds during the regular season while averaging 52.3% shooting from the field.

He was a major contributor during the Bucks' run to the NBA championship, averaging 8.8 points and 5.0 rebounds during the postseason.
