USC wide receiver Vidal Hazelton played the 2007 season with what he thought was a groin injury, leading the team with 50 receptions for 540 yards and four touchdowns.
But it turned out he played the season with a more serious injury -- two tears of his stomach muscles
Hazelton recently underwent abdominal surgery for the injuries and is expected to be fully recovered in time for spring practice, according to Los Angeles-area media reports.
The surgery was performed in Philadelphia by Dr. William Meyers of Drexel University, according to reports. While USC usually doesn't send its student athletes east for treatment, Hazelton's family insisted upon an expert in abdominal surgery performing the procedure.
