The Philadelphia Eagles signed quarterback Trent Edwards to a one-year contract extension on Wednesday, keeping him with the club through the 2013 season.

Edwards was originally signed to a one-year deal in the offseason, but battled his way onto the final 53-man roster thanks to an outstanding showing in the preseason, which forced the release of 2010 fourth-round draft pick Mike Kafka.

Edwards, 28, was 54-of-80 through the air in the preseason, good for 489 yards, four touchdowns and no interceptions.
