New York Rangers defenseman Adam Fox is going on injured reserve with an upper-body injury, a person with knowledge of the decision tells The Associated Press.

The Rangers’ chances of beating out the crowded field vying for a playoff spot will be a little bit more challenging now that they will be without top defenseman Adam Fox, who was placed on injured reserve Wednesday with an upper-body injury. Fox will miss at least a week and perhaps more.

New York Rangers defenseman Adam Fox is heading to the injured reserve list due to an upper-body injury, according to multiple reports on Wednesday. Fox injured his left shoulder during a third-period fall of Tuesday's 5-1 victory over the New York Islanders.
