Upshall could miss up to six weeks with wrist injury
Upshall and Umberger were both hurt in Philadelphia's 4-2 loss against Ottawa on Tuesday night and the Flyers said both players were scheduled for surgery Thursday.
Upshall was acquired from Nashville at last year's trade deadline in the Peter Forsberg deal and finished with eight goals and 16 points last season.
Umberger broke the pinky finger on his left hand.
