The center fielder told his side of the story during a teleconference with MLB officials last Friday but had not heard a decision as of Wednesday afternoon.
He was not in the lineup Wednesday due to tightness in his back that forced him to leave the Brewers' game Tuesday against the Pirates after six innings.
Speaking to the media before the game, neither Gomez or manager Ron Roenicke suggested that the appeal would be dropped.
Gomez will be eligible to return Saturday, when the Brewers face the Cubs in the second of a three-game series at Wrigley Field.
The team's leadoff hitter this season, Gomez was hitting .290 with nine home runs and 21 RBI. He started all 39 games this season and is fourth in the National League with 21 extra base hits.
