Two men fished out of Charles River at 3 a.m.

The Boston Fire Department reports firefighters pulled two guys out of the middle of the river by the Mass. Ave. Bridge early this morning. After rescuers put life rings around them both and got them out of the water, they were taken to the MIT boathouse for evaluation by EMTs.

Boston Police, who had their own boat on the scene, reports both men, one 22, the other 21, were pulled from the water "conscious and alert" with what appeared to be "a mild state of hypothermia." The two were taken to Mass. General.

"Unclear how they got there," BFD says. BPD wouldn't hazard a guess, either.
