San Francisco 49ers quarterback Colin Kaepernick is being investigated for a possible sexual assault at a hotel in Miami, Florida ... law enforcement sources tell TMZ Sports.
We're told the alleged incident took place at the Viceroy Hotel in Miami earlier this month.

Our sources tell us ... the investigation is in its "beginning stages" and no charges have been filed against anyone at this point.

We reached out to both Colin's agent and the San Francisco 49ers -- so far, no comment from either one.

Kaepernick doesn't appear to be fazed by the allegations -- he was out partying at a Miami nightclub early Sunday morning with a smile on his face.

Colin was at the Viceroy as recently as April 5th -- when he hung out with a wedding party near the pool at the hotel. People in the wedding party tell us Colin couldn't have been nicer and "made the bride's weekend."

Update:

The Miami PD has released an "information report" ... showing the alleged incident took place on April 1.

According to the report, two other individuals are being questioned -- both NFL players.

SF wide receiver Quinton Patton and Seattle Seahawks wide receiver Ricardo Lockette.

According to the report, the alleged incident took place at Lockette's apartment in Miami.

Sources say the alleged victim later went to the Viceroy Hotel.

Kaepernick was hanging out with Lockette at a nightclub in Vegas just two weeks ago ... days before the alleged sexual assault.

Update:

TMZ Sports has obtained a police report filed after the alleged incident ... in which the accuser claims the alleged incident took place at at a residence at the Viceroy Hotel on April 1.

According to the report, issued by the Miami PD, the woman claims she went to the apartment of Seattle Seahawks wide receiver Ricardo Lockette ... to hang out with him, Kaepernick and 49ers wide receiver Quinton Patton.

The woman told police, around 9pm that night she mixed some drinks for the guys and gave them shots, but they told her that "in order to drink the shots she had to 'hit' the bong which contained marijuana."

The woman says she felt lightheaded and went to the bedroom to lie down. She claims Kaepernick "came up behind her into the bedroom and started kissing her."
"She advised they were kissing (mouth) and Mr Kaepernick started to undressed [sic] her. She got completely naked. Mr. Kaepernick told her that he was going to be right back and left the bedroom. They did not have sex."

The woman told cops that while she was still naked in bed, Patton and Lockette opened the door and "peeked" inside. She says she told them to get out ... but she can't remember anything after that.

The woman later woke up in a hospital bed ... but says she doesn't remember how she got there or who took her there.
