Doc Rivers did not have Bobby Portis in the Milwaukee Bucks lineup on Thursday against the LA Clippers. The sixth-man extraordinaire for the Bucks began serving a 25-game suspension, the NBA's punishment for failing a drug test. The fan-favorite admitted taking Tramadol, which is an opiate, to reduce pain and inflammation in his elbow.

Portis is one of the league's top bench producers, and he adds even more intangibles. Milwaukee will need other players to step up.

MILWAUKEE -- Milwaukee Bucks forward Bobby Portis has been suspended for 25 games for taking a banned substance, the NBA announced on Thursday. Portis tested positive for a painkiller called Tramadol, and will begin his suspension on Thursday when the Bucks host the Los Angeles Clippers .
