Kamara had been relatively unspectacular during his roughly three-month stay. The Sierra Leone international had one goal and one assist, as Norwich City went 2-5-4 during his time there. The most recent loss to Aston Villa left them on 38 points, just three points clear of the drop zone.
Forced to make a choice sooner than later, it's entirely possible that Norwich City simply didn't feel as though Kamara was worth whatever it would have cost to make the move permanent, especially with the possibility of playing in the Championship next season.
In Kamara's absence, KC has gotten off to a bit of an even start. While their 14 points through nine matches puts them in the thick of the Eastern Conference race, they only have scored 10 goals. Kamara led KC with 11 goals and was second on the team with eight assists in 2012.
