Lampard was sent off after an assistant referee told match ref Peter Walton that he slapped Luis Boa Morte in the face.
Chelsea will argue it was a gentle shove in the chest and worthy of no more than a yellow card.
As long as Walton accurately recounts the same version in his match report, then the automatic red card will be downgraded.
Captain John Terry said: "It was very harsh. Peter Walton is a very clever referee and very good as well. I'm sure he'll look at it again."
