Milwaukee Police say a motorcycle rider is in stable condition after crashing into a semi this afternoon at 91st and Good Hope.  Police say early indications are that the motorcycle rider may have run a red light.

A witness tells Newsradio 620 WTMJ that one of the semi's wheels was on top of the bike.  The witness says the biker also appeared to be under the truck.

Authorities were able to get the bike out from under the truck, and damage to the bike didn't appear to be too serious.  The witness says the bike appeared to be a larger touring bike.
