Giroux sustained tendon damage when a golf club shattered and splintered into his finger Thursday. It's unknown what caused the club to shatter.
Giroux is expected to make a full recovery in five to six weeks. Last month, Philadelphia signed Giroux to an eight-year contract extension worth over $64 million.
Giroux was hurt playing overseas during the lockout last year and finished with only 13 goals and 48 points for the Flyers. He has 291 points (91 goals, 200 assists) in 333 career games spread over six seasons in Philadelphia.
