Patton and Lockette also involved in alleged incident.
San Francisco 49ers star Colin Kaepernick and two other NFL players are being investigated by Miami police for an incident earlier this month at a Miami hotel.
Police confirmed on Thursday that there is an investigation but would not release any further details on the matter in terms of the exact nature of what they are looking into, ESPN report.
No arrests have yet been made and no charges have been filed, but it is understood that an unnamed woman said she had an encounter with the 49ers quarterback as well as wide receiver Quinton Patton and Seattle Seahawks receiver Ricardo Lockette.
The incident is supposedly said to have taken place on April 1 at the Viceroy in downtown Miami, and the woman has reportedly told police that she spent time with the three NFL stars drinking and smoking marijuana before eventually ending up in a bedroom with Kaepernick.
According to the report, the woman has told police that while both she and Kaepernick undressed, they did not have sex and that he eventually left the room while the other two individuals later opened the door and “peeked” into the room but closed it and left after she told them to get out.
TMZ.com earlier reported that Kaepernick is being investigated for an alleged sexual assault, but the Miami Police Department have since stated that the website “took the report out of context”.
49ers general manager Trent Baalke revealed in a statement that the organisation is aware of the incident and are in the “process of gathering the pertinent facts” while the Seahawks also released a similar statement regarding Lockette.
It remains to be seen what the truth is behind this story, and currently all the above is alleged and no arrests have been made.
