The former Houston Rockets star, who is on leave from his job as an analyst on Rockets telecasts, also was arraigned on three counts of aggravated sexual assault and three counts of indecency with a child, Assistant District Attorney Lance Long said.
"Calvin adamantly insists that he is innocent of these charges and is anxious to present his side to a jury at trial," said Rusty Hardin, Murphy's attorney.
Hardin said the indictment was expected and "it is important for everyone to remember that the grand jury has not heard from Calvin nor many witnesses on his behalf that insist these allegations are absolutely untrue."
Murphy initially was charged March 29 after five daughters accused him of sexually abusing them between 1988-1991, when they ranged in age from 6 to 13. Murphy, 55, has contended the allegations stem from a family battle over money, an explanation Long has dismissed.
He remains free on $20,000 bail. If convicted, Murphy could receive five years to life in prison for the aggravated offenses and two to 20 years for the indecency violations. He also could be eligible for probation because he does not have a criminal history.
Murphy, a guard for the Rockets from 1970 to 1983, has 14 children by nine women.
During his tenure with the team, he missed just nine free throws, and in 1980-81 made 78 straight in one stretch for a record single-season percentage of .958.
The 5-foot-9 player averaged 17.9 points and shot 89.2 percent from the line during his NBA career. He was a high school star at Norwalk, Conn., before moving on to Niagara University, where he averaged 33.1 points.
He was drafted in the second round in 1970 by the San Diego Rockets, who moved to Houston the following year. His 17,949 points were a franchise high until Hakeem Olajuwon surpassed him.
Murphy was inducted into the Basketball Hall of Fame in 11 years ago and his number hangs retired at Toyota Center.
