Attorney David Lane told 9NEWS pitcher Vicente Padilla was accused of attending a club with a woman and then slapping her when they went back to his downtown Denver hotel.
Denver Police say the incident happened just before 4 a.m. at the Ritz Carlton in downtown Denver.
Denver Police say the investigated the allegations and did not find enough evidence to recommend that charges be filed against Padilla and say he will not be arrested.
The Dodgers are in Denver for a series with the Colorado Rockies. Padilla is currently on the Dodgers' 15-day disabled list and is not on the team's active roster
Padilla was the opening day starter for the Dodgers but went on the 15-day disabled list in April because his upper right forearm muscle was bothering him. He had been scheduled to throw a simulated game at Coors Field.
The Dodgers issued a statement saying they are aware of the allegations against Padilla but would not comment "on a pending legal matter."
