Lopez is out of the lineup for Sunday's game against the Tigers, Alec Lewis of The Athletic reports.
Hanser Alberto will pick up the start at shortstop for the lefty-hitting Lopez, who takes a seat with southpaw Tarik Skubal on the hill for Detroit. Lopez had started in each of Kansas City's first 17 games of July, slashing .339/.413/.429 with zero home runs, one stolen base, nine runs and 10 RBI.
