The second-degree assault charge against Bullis football coach Patrick Cilento was dismissed Friday by the Montgomery County State’s Attorney’s Office.

“Today we entered a dropping of the charges . . . we could not entertain full evidence or corroboration of the case, so we weren’t be able to prove in Court that there was an assault,” said Ramon Korionoff, a spokesman for the state attorney’s office.

Cilento had been charged following an alleged incident involving his wife, who filed a complaint in early June. An arrest warrant was issued for Cilento, 41, who voluntarily met with police, posted bond and was released the same day.

“Mr. Cilento is happy that the State’s Attorney’s Office dismissed the charge filed against him by his wife as the facts did not support any criminal conduct,” Cilento’s attorney, Rene Sandler, said. “The police had already determined that no charges were warranted at the time his wife filed her complaint against him. Mr. Cilento looks forward to his return to the football field to lead his Bullis team to victory.”

Cilento has been on administrative leave since the complaint was filed in June, and Bullis representatives were not available to comment Friday.

Cilento has been the head football coach at Bullis since 2010, training some of the Washington region’s top athletes, including quarterback Dwayne Haskins, the Washington Redskins’ top draft pick in April’s NFL draft.

In her complaint, Cilento’s wife said the incident stemmed from a conversation that turned into an argument. In her complaint, she said while she tried to console their three-year-old child, she felt a “sharp shoulder/elbow shove” and was pushed down concrete stairs at their home. The complaint states that she suffered a scrape on her right elbow, soreness on her right hip/rib cage and a bruise on the outside of her left knee as a result.
