The Flyers officially signed right wing Mike Knuble to a one-year contract Friday, and the veteran will be available for Saturday's game at the Florida Panthers.

Knuble , 40, returns to the Flyers after spending the past three seasons with the Washington Capitals. He played for the Flyers for four seasons (2005-2009) after signing as a free agent July 3, 2004. Knuble appeared in 310 games for Philadelphia, recording 114 goals and 221 points.

The move for Knuble was necessitated by an injury to Flyers forward Scott Hartnell, who is expected to miss four to eight weeks because of a broken left foot. Hartnell, an All-Star last season who finished with 37 goals and 67 points, was injured by a shot taken by teammate Kimmo Timonen in Tuesday's game against New Jersey. Hartnell had one point in three games.

The Flyers (1-3) also recalled defenseman Andreas Lilja, 37, from the AHL, and he will be in the lineup as well, vs. the Panthers.
