Flyers center Daniel Briere will be sidelined up to a month because of a torn abdominal muscle, according to an Associated Press report on Monday. ?It?s definitely tough to take but what can you do,? Briere said in a telephone conversation with a Philadelphia pool reporter. ?I?m not going to sit around and sulk or pout about it. I have to focus on getting better and picking up where I left off.? Briere, who signed with the Flyers as a free agent last year, is scheduled to have surgery Saturday.
