USC Athletic Director Pat Haden underwent an unspecified medical procedure Thursday and was expected to remain hospitalized for another day or two, a person with knowledge of the situation said.
Haden, 63, was hospitalized Wednesday after feeling lightheaded outside Heritage Hall. Paramedics took him to one hospital where he was later discharged. Haden then went to another local hospital and spent the night there before Thursday's procedure.
Haden, who has a pacemaker, was resting comfortably after Thursday's procedure, said the person with knowledge of the situation, who requested anonymity because of the sensitive nature of the situation.
