NEW YORK -- A woman has accused new Bears receiver Brandon Marshall of punching her in the face at a nightclub, New York City police said.

The woman alleged the incident occurred at 3:50 a.m. ET Sunday outside the Marquee, a nightclub in Manhattan's Chelsea neighborhood, police said. Police are investigating a complaint the woman filed Monday evening. Marshall has not been charged.

In a statement, Bears general manager Phil Emery said the team was aware of the alleged incident when it obtained Marshall from the Miami Dolphins on Tuesday.

"Both the Bears and Dolphins were aware of what occurred over the weekend. We decided to move forward with the trade. We have high expectations for Brandon as a Bear," Emery said.

A source, however, told ESPN NFL Insider Adam Schefter that although the Bears knew there was an incident involving Marshall, the team didn't know the details or that he was being investigated by police.

Marshall's attorney, Harvey Steinberg, said in a statement early Wednesday morning that Marshall and his friends were not involved in the melee.

"Brandon Marshall was the keynote speaker at a charitable event in New York. After the event was over he, his wife and close friends attended a function at a local club," the statement said. "While at the function a fight broke out NOT involving Mr. Marshall or his friends."

Marshall allegedly got into an argument with a group of friends celebrating a birthday at the club, the New York Post reported. According to the Post, Christin Myles, the woman celebrating a birthday, briefly left an upper floor of the club. Upon returning, the paper reported, Myles was told to wait because Marshall allegedly was involved in a fight with an unnamed football player and both players were being removed from the club.

Myles eventually met with her friends outside, the Post said, and found the 6-foot-4 Marshall and the unnamed player arguing with her group. Marshall then allegedly punched Myles in the left eye, leaving her with a black eye, according to the Post. It wasn't clear if Marshall intentionally struck Myles or if he meant to hit one of her friends, according to the report.

Steinberg said that while Marshall and his wife were attempting to leave the club, Marshall's wife was hit in the face with a bottle and suffered "serious" injuries that required hospitalization.

Steinberg said Marshall would cooperate with the investigation.
