If it is late in the season, it is just going to sleep for the winter. It will return in the spring.

Can I save a yellow leaf?

Once a leaf turns fully yellow, it will not turn green again. It is best to let the plant shed it naturally.

Check these first

Feel the soil to see if it is wet or dry.
Check the calendar to see if the plant is entering dormancy.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil will likely feel soggy or smell slightly sour.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the soil is waterlogged, repot the plant into fresh, well draining soil.
Seasonal Dormancy
Possible
How to tell: The entire plant begins to yellow and die back as the season ends. This happens naturally in late summer or autumn.
What to do: Reduce watering significantly as the plant prepares for its winter rest. Allow the stems to die back naturally before trimming them to the ground.
