Danica Patrick hit by rock
Patrick got smacked by a stray rock while attending a race Thursday night, leaving her with a sore head. She had a brief conversation with medical staff Friday, but felt no problems.
Patrick says the rock hit her ''straight in the head,'' and she's glad she had a hat on or ''there would have been blood.''
Patrick had one of the most significant crashes of her career last Sunday in Phoenix, slamming into a wall with about 100 laps left and leaving her with a stiff neck and a headache.
Patrick became the first woman to win a pole and lead green-flag laps at the Daytona 500 last month, finishing eighth.
