The Toronto Maple Leafs have announced that forward Nazem Kadri will not return to the game against the St. Louis Blues after sustaining a concussion in the first period. Kadri will be re-evaluated on Wednesday.

It’s uncertain when Kadri suffered the concussion exactly. However, he was on the receiving end of a few big collisions. This includes one where he was absolutely levelled by St. Louis Blues defenceman Vince Dunn. It was first announced that he was being held out for precautionary reasons but later revealed that he had, in fact, sustained a concussion.

In 58 games so far this season, Kadri has scored 15 goals and added 20 assists for 35 points. He also has an outstanding Corsi-For percentage of 60.6 percent.

Over his career with the Leafs, Kadri has scored 160 goals and 188 assists for 348 points in 546 games.

Kadri was originally drafted the Leafs in the first round, seventh overall in the 2009 NHL Entry Draft.
