Manager Dave Martinez said Rendon underwent an MRI on his elbow Sunday, Jesse Dougherty of The Washington Post reports.
The MRI came back clean, confirming Rendon is simply dealing with a bruised elbow. Still, Martinez noted that a trip to the injured list could still be necessary if the third baseman -- who is out of the lineup Monday for the seventh time in eight games -- isn't ready to rejoin the lineup in the coming days.
