The arraignment hearing has been delayed three times and the case remains in the discovery process, said Hardin, who is trying to obtain any video footage that might show Bennett entering the field.
Bennett's representatives are hoping the case will be dismissed before the start of the regular season, Pelissero reported. If the case moves forward, a trial likely wouldn't take place until after the season ends, but there's a chance it could take place during the season.
The Philadelphia Eagles defensive end has yet to enter a plea on the charge, but Hardin told reporters in March his client would plea not guilty if the case moved to trial.
The Harris County District Attorney's Office accuses Bennett of injuring a 66-year-old paraplegic woman who was working to control access to the field during the game. Prosecutors claim Bennett, 32, injured the victim after he pushed his way onto the field after being told to use another entrance for field access.
Bennett denies ever touching the woman.
"He didn't do this," Hardin told Pelissero in March. "He never touched anybody. And it is so totally contrary to his entire life and career."
The specific charge Bennett is facing -- injury to the elderly -- includes intentionally and knowingly causing bodily injury to a person 65 years or older. It carries a maximum penalty of up to 10 years in prison and a $10,000 fine.
The 10-year veteran could be subject to potential NFL discipline under the league's personal conduct policy.
