It happened as the officers were investigating a teenage bicyclist that was hit by a garbage truck near Palisade Avenue and 30th Street around 9 p.m.
The teen was pronounced dead at the hospital.
Two motorcyclists were driving together and one struck the officers.
All three of the injured officers are expected to survive and their exact conditions are not yet known.
One of the motorcyclists fled the scene, while the other also crashed into the garbage truck that was involved in the initial accident.
That motorcyclist was taken to the hospital with non-life threatening injuries.
At this point, it's not yet clear which of the motorcyclists hit the officers.
There is an active investigation underway.
