Gonzalez was to speak with Gwinnett manager Brian Snitker on Sunday afternoon just to make sure Gattis is not dealing with any stiffness or pain in his back.
Gattis, who has been sidelined since first feeling the effects of a bulging thoracic disc on June 27, played the fourth and likely final game of his rehab assignment with Triple-A Gwinnett on Sunday afternoon.
Regaining timing at the plate was the main concern for Gattis, who made it through his time in Gwinnett pain-free while catching 12 innings and tallying 16 at-bats.
Gattis finished 2-for-6 with two singles, two RBIs, two runs scored and three strikeouts as the designated hitter on Sunday, showing the improvement at the plate after going only 1-for-10 with an infield single and four strikeouts in his first three games.
