Can a priest give a Mass in American Sign Language (ASL)? What does he do when he is supposed to lift up the Eucharist while speaking in ASL?

Part of the mass involves the priest lifting up the Eucharist and saying the following aloud: > Behold the Lamb of God, behold him who takes away the sins of the world. Blessed are those called to the supper of the Lamb. In the event that the priest is saying the mass using English sign language (as opposed to saying it in a verbal language and having an interpreter repeating his words in sign language), what does he do? He can't both hold up the Eucharist and say the words with his hands. Does he lift up the Eucharist, set it down, and then say those words? Does he do the opposite? Is there some other way this situation is to be handled? (I'm guessing that there's an answer somewhere in canon law, since surely someone has run into this situation).
