He said that the accusations, should they result in charges, would be vigorously contested.
"We'll defend those if and when they become charges," Amendola told the AP in a phone interview Wednesday. "We'll defend those just like we're defending the other charges."
Sandusky, 67, is charged with sexually abusing eight boys, some on campus. He has said that he showered with some boys but never sexually abused them.
The Patriot-News of Harrisburg has reported that the pair of new claims were brought within the last two months.
Lawyers for two other people arrested earlier this month as a result of a grand jury investigation into allegations against Sandusky are asking prosecutors to turn over material to help them prepare for a preliminary hearing next month.
Attorneys for Penn State athletic director Tim Curley and former university vice president Gary Schultz wrote to state prosecutors Tuesday asking for grand-jury testimony and other information related to their cases. They faces charges of perjury and failure to properly report suspected child abuse; they maintain their innocence.
Among other things, they asked for corroboration of statements by assistant coach Mike McQueary that he told Schultz and Curley that he witnessed Sandusky sodomizing a boy in the football team showers nine years ago.
The letter suggests that a key element of that defense is likely to be a challenge to the testimony of McQueary, who a grand-jury report said told the administrators during a meeting "that he had witnessed what he believed to be Sandusky having . . . sex with a boy."
Meanwhile, a source close to the family of fired football coach Joe Paterno confirmed to the AP on Wednesday night that Paterno's wife, Sue, was asked to leave a campus pool, leaving the avid swimmer saddened. School spokesman Bill Mahon said that he had not heard of such a directive.
Paterno was focused on beating his lung cancer and seeing the "full truth emerge," the source said.
The family was getting calls, letters and visits from ex-players and friends.
Sandusky's modest home at the end of a dead-end street in State College has been staked out by camera crews since the scandal began.
A window has twice been broken at the house, and police patrol the area regularly.
Amendola said that it's a "very difficult time" for Sandusky and his family.
"It's just heartbreaking from their perspective, to see these allegations basically result in the crumbling of his life's work," he said.
Sandusky is essentially homebound, and the family fears facing people who might "take some sort of assaultive-like actions," Amendola said. Asked if Sandusky feared for his safety, the lawyer said, "Well, he does, yes, of course."
The scandal also resulted in the departure under pressure of President Graham Spanier and has brought shame to one of college football's legendary programs.
Curley has been placed on administrative leave, and Schultz, who was in charge of the university's police department, has stepped down.
