Gattis was hoping to return at some point this weekend, with the Braves wrapping up their 10-day, nine-game road trip with a three-game series against the Rangers. He saw a doctor on Saturday afternoon, but remained unlikely to play on Sunday.
Meanwhile, Jason Heyward was taken out of the leadoff spot in a late lineup shift before the Braves' 3-2 loss to the Rangers on Saturday. He was initially penciled into the No. 1 spot, but Gonzalez moved him from first to fifth in the lineup about 45 minutes before first pitch. A career .282 hitter as a leadoff man, Heyward entered Saturday batting .270 in the leadoff spot this season while hitting .291 when batting fifth.
He was replaced in the leadoff spot by Emilio Bonifacio, who was originally batting ninth. Christian Bethancourt started at catcher for the fourth consecutive contest and batted sixth. Rookie second baseman Tommy La Stella batted seventh, while making his first career start as a designated hitter.
Gattis, who attended Bishop Lynch High School in Dallas, is batting .270 with 22 home runs -- second-most among Major League catchers -- and 52 RBIs in 102 games this season.
