Bobby Portis

Portis entered the starting lineup for this game, and if he remains there, fantasy managers should enjoy a long stretch of strong production. He fell two assists shy of a triple-double but still recorded his first double-double in nearly three weeks. Portis is currently rostered in just 37 percent of Yahoo! leagues, but with Giannis Antetokounmpo (calf) set to miss an extended period of time, Portis should be considered a must-roster player as long as he's starting.

Portis will enter the starting lineup, which will push Gary Harris to the bench. Harris had started the last two games for the Bucks but didn't offer much value for fantasy managers. Portis should be able to do more in the box score as a starter and could remain in that role with Giannis Antetokounmpo (calf) sidelined for a while.

Portis is in the starting lineup for Tuesday's matchup with the 76ers.

According to Nehm, Rivers said, "He did a very good job. MRI has revealed exactly what we thought. There's no timetable. Calf strain and really no timetable for return. Hopefully, like it was before, sooner (than later), but there's no timetable." That's certainly a divergence from Giannis' initial four-to-six-week estimate. Until Antetokounmpo returns, Bobby Portis and Kyle Kuzma will share duties at PF.
