According to the St. Louis Post-Dispatch, Clampett was taken off the broadcast after the comment.
Clampett, working the Internet broadcast of Amen Corner at Augusta National Golf Club, made the comment Friday after Liang missed the cut.
"It has been a privilege to be here with you the last two days describing action of all of the players," Clampett said in a statement released Monday. "In describing the Asian player Wen-Chong Liang, if I offended anybody, please accept my sincere apology."
Liang, who missed the cut by six strokes after shooting rounds of 76 and 78, was playing in his first Masters on a special foreign invitation.
Clampett also works golf telecasts during the PGA Tour season for CBS.
