If all the other leaves are healthy then I wouldn't worry about it - I remove the lower leaves of my tomatoes anyway so that they don't pick up stuff from the soil if they get splashed while watering, so I'd take them off if I were you.

If more leaves were discoloured I'd be looking at a nutrient deficiency or overwatering, but with yours it's probably because those are the oldest leaves and they're on the way out anway.
