Moreno was diagnosed with a left groin strain after exiting Monday's game against Cleveland.
Moreno will likely require a trip to the 10-day injured list following this diagnosis, though it's still too early to determine exactly how much time he'll miss. Jose Herrera is the only other catcher on the 40-man roster, so it looks like the D-Backs will promote either Adrian Del Castillo or Ronaldo Hernandez from Triple-A Reno to serve as the backup catcher until Moreno returns to full strength.
