Bucks guard Matthew Dellavedova has been diagnosed with a grade 3 right ankle sprain and is expected to be sidelined for the next three or four weeks, league sources tell ESPN’s Chris Haynes (Twitter link). Dellavedova suffered the injury during the fourth quarter of Sunday’s game against Brooklyn. Dellavedova, 27, has seen his minutes cut back during his second season in Milwaukee. After playing a career-high 26.1 MPG in 76 regular season contests a year ago, Dellavedova is averaging just 19.0 MPG this season, his lowest mark since his rookie season.
