2010-11: Manning was in the New York Rangers training camp but not signed and returned to Chilliwack as a 20-year-old.

Manning skated in all five playoff games and was -2 with 1 goal and 8 PMs. Philadelphia signed Manning to a three-year, entry-level contract in November 2010.
2011-12: Manning made his NHL debut – appearing in four games for the Flyers during a March call-up – after skating for Philadelphia AHL affiliate Adirondack in his first pro season. He had no points and was plus-one averaging just under 14 minutes of ice time in his stint with the Flyers. Manning missed pre-season camp and the first half of the season due to an undisclosed injury; making his debut with the Phantoms against Norfolk on December 3rd. He scored 6 goals with 13 assists and was minus-six with 81 penalty minutes in 46 games for Adirondack. The Phantoms missed the AHL playoffs; finishing fifth in the Northeast Division.
