Narrative:

During pre-flight I did the walk around and did not find any problems with the aoa (angle of attack) sensors or anything else with the aircraft. I actually did a second inspection to finish the first flight of the day checks that needed to be completed. (We had already done an originating flight and I didn't know this aircraft was originating until I saw the paperwork.) captain did a successful stall protection system (sps) test on the ground. Shortly after applying take-off thrust we received a red sps 1 fail message on EICAS and we aborted the take-off. Speed was well below 80kts. After clearing the runway the messages cleared. We contacted operations and maintenance. Maintenance advised us to return to gate to have maintenance check the aircraft. Once we arrived at the gate we found that the aoa sensor on the captain's side had been damaged. Operations was able to swap us an aircraft and we completed the flight in the new aircraft.
