Pollock, 43, is the owner of Kokopellis Gym in Longwood, where  Zimmerman once trained. Pollock was arrested March 11 by police in Longwood and charged with misdemeanor battery, according to his lawyer, Paul Ghezzi.

Although it was initially reported that Pollock was charged with felony battery by strangulation, false imprisonment and aggravated assault with a deadly weapon, Ghezzi told Crimesider on July 12 that those charges were never officially filed, despite the fact that they were stated on his booking report.

Ghezzi further stated that Tina Mangiardi, the woman who  pressed charges against his client, has "no credibility whatsoever."

ABC affiliate WFTV reports Mangiardi pleaded guilty in March after being accused of taking more than $2 million from investors as part of a Ponzi scheme. Pollock was one of her investors, the station reports.

According to the station, Mangiardi told police she arrived at Pollock's gym to pay a debt she owed him when Pollock put on a pair of black gloves and pulled out a knife. Mangiardi reportedly told police Pollock threatened to cut off her fingers and toes as collateral.

Pollock was booked at the Seminole County Jail and remained in custody for four days until March 15 when he was released on a $2,750 bond. According to Ghezzi, although Pollock was initially ordered to wear a GPS monitoring system as part of his release agreement, that was withdrawn when Mangiardi refused to provide an address to the court.

"She completely refused to cooperate," Ghezzi told Crimesider.

Jury selection in the case is scheduled to begin on July 29, but Ghezzi says he doesn't think the case will make it to trial.

"My client is completely innocent and I believe he will be exonerated," Ghezzi said.

He said that Pollock will not comment on the case at this time because he is currently under subpoena.

On Monday, July 8, Pollock testified in Zimmerman's murder trial that the former neighborhood watch volunteer was an unaccomplished fighter and was "physically soft."

Zimmerman is charged with second-degree murder in the February 2012 fatal shooting of 17-year-old Trayvon Martin. He claims he shot the teen in self-defense but prosecutors argue that Zimmerman profiled Martin as a criminal and started the confrontation.

"He was an overweight, large man when he came to us, a very pleasant, very nice man, but physically soft - predominantly fat," Pollock testified. "Not a lot of muscle. Not a lot of strength."

"He was about a 1," said Pollock, when asked to rank Zimmerman's athletic skill on a scale of 1 to 10.

Pollock's own legal battles were not mentioned during his testimony.
