Tellez (kneecap) is expected to spend a minimum of two weeks on the injured list, Tom Haudricourt of the Milwaukee Journal Sentinel reports.
Tellez was diagnosed with a strained right patella after he left Saturday's game against Cleveland, and manager Craig Counsell said Sunday that the first baseman will be reassessed after two weeks. With three weeks remaining in the regular season, the 26-year-old faces a tight window if he hopes to return to game action prior to postseason play.
