Witnesses told FOX 5 the victim held onto the black Lexus SUV for about "100 yards" before the suspects finally put it in reverse in an effort to dislodge him.
Police say the two suspects drove up to the SUV at Pullman Place near Whetstone Glen and Girard streets in a Chevy Malibu when the victim noticed them.
When the victim saw the suspects trying to steal the vehicle, he reportedly jumped on it.
Police say the victim is in serious condition - but they expect him to survive.
Police say they have since recovered the Lexus.
If you can help police find the suspects, they want to hear from you.
