McMahon is out of the lineup for Sunday's game against the Twins.
The veteran third baseman returned from the injured list Friday after missing time due to a throat and ear infection, and he went 1-for-5 with two walks, a double and two runs in his first two games back in the lineup. McMahon will rest for Sunday's series finale, which allows Anthony Volpe to start at shortstop while Jose Caballero mans third base.
