Boston Red Sox third baseman Pablo Sandoval (knee) will undergo an MRI on Monday.
Sandoval was initially listed as day-to-day with a right knee sprain after he was forced to leave Sunday's contest early against the Baltimore Orioles.
Sandoval is slashing .213/.269/.377 across 67 plate appearances this season with three home runs and 10 RBI's.
