The only acceptable 2-letter SCRABBLE® word that ends in "g" in American tournament play is: ag.
Ag means "pertaining to agriculture". It is an abbreviated form of the word, just like ad (advertisement) and za (Pizza), which are also acceptable SCRABBLE® words.
Errata: Abbreviations are NOT acceptable in SCRABBLE. In WORDS WITH FRIENDS you can usually get away with abbreviations (AG) and "sound effect words" (UG, UH, AH, etc). So, the 2 acceptable words are AG and UG.
