When asked if Decker's injury could be season-ending, Jets coach Todd Bowles said he was "not sure."
"I'm not sure," Bowles told reporters, via the New York Post. "They have to monitor it. [Doctors] said some people play with it over the course of time. We'll see how it goes."
Decker is likely to miss multiple weeks. The 29-year-old had 1,027 yards and 12 touchdowns on 80 catches last season. He has 194 yards and two touchdowns on nine receptions in 2016.
While this is a big blow to fantasy football players who own Decker, some solace could be found in Quincy Enunwa, who has established himself as a steady WR3 opposite Brandon Marshall.
