NORTH BAY VILLAGE, Florida (CNN) -- A packed deck of Shuckers Bar & Grill, a popular sports bar in Florida, collapsed into Biscayne Bay, sending patrons into the water late Thursday night.
About 100 people are believed to have been on the deck at the time of the collapse, Miami-Dade Fire Lt. Eugene Germain told reporters.
Authorities are treating 24 victims, three of whom have "critical injuries," Germain said. Officials believe no one is missing.
Video showed fire trucks and ambulances at the scene, which was illuminated by a spotlight from a helicopter. Rescue divers were also there. At least one patient on a stretcher was put inside a waiting ambulance.
The collapse is believed to have happened shortly before 9:00 Thursday night, Topeka time. Connected to a Best Western hotel, Shuckers Bar & Grill is in Miami's North Bay Village.
On its website, it boasts outdoor dining on a dock over Biscayne Bay and 23 high-definition flat-screen TVs -- many of them, no doubt, tuned to Thursday night's NBA Finals showdown between the San Antonio Spurs and the hometown Miami Heat.
What had been the deck was largely unrecognizable after the collapse, video from CBS4Miami, WFOR-TV showed.
Leah Masters, a Shuckers hostess, told the affiliate the deck collapsed just as people stood to cheer a Heat basket.
