Last week's injury is a mild strain of his right patellar tendon. Hibbert has been examined by Pacers' medical officials, and they've cleared him to renew summer workouts immediately.
Hibbert and Danny Granger are the team's young building blocks. Hibbert averaged 11.7 points and 5.7 rebounds a game last season in his second year in the NBA.
He shot 50 percent from the field and started 69 of 81 games.
