D'Arnaud (thumb) was reinstated from the 60-day injured list Wednesday.
D'Arnaud's was unable to make his final rehab appearance at Triple-A Gwinnett on Tuesday since the game was postponed due to inclement weather, but he'll still make his expected return from the 60-day IL a day later. The 32-year-old appeared in six rehab games and went 4-for-17 with two runs, an RBI and two walks. He'll reclaim his job as Atlanta's primary catcher, while Kevan Smith was designated for assignment Wednesday.
