Sean Couturier will open the 2011-12 season on Philadelphia's third line. Brayden Schenn has been demoted to the minors, on what appears to be a temporary salary cap basis, so Couturier will make his NHL debut on Thursday night in Boston against the defending Stanley Cup champions. If the top-six forward group from Tuesday's practice remains unchanged then he will be between Matt Read and Scott Hartnell in Philadelphia's regular season opener.
