Spanish Red Cross spokesman Jose Aldaba said one person was gored in the chest and another in the leg in today's run.
There were no immediate details on their identities or the gravity of their injuries. Several people were treated for other injuries in the race.
Tension soared when one bull got separated from the pack in the final 100 meters and tried to charge runners on all sides.
Fifteen people have died from gorings since record-keeping began in 1924.
