According to ESPN's Jane McManus, the second-year quarterback almost did just that, as he hid his symptoms for the better part of this week:
His teammates did.
According to several players McElroy confided in, the quarterback had been wrestling for days with the decision to tell the Jets' medical staff of his symptoms.
McElroy, according to the report, confided in wide receiver Clyde Gates and offensive lineman Matt Slauson, who both have suffered concussions in the past.
Gates told McElroy to divulge the information to the Jets' higher-ups while Slauson revealed that he had worked through a past concussion without telling anyone.
There has been endless talk about who—between Sanchez, McElroy and Tim Tebow—should be starting under center for New York, and as such, a lot of pressure resides on all three players.
It's understandable that McElroy, who was described as a "warrior" by Slauson, would want to play through the pain, but it's important to remember what's at stake here.
Playing through a concussion has the potential to negatively impact a player for the rest of his life, and it's something that probably happens too often in sports.
This had the potential to be a devastating story if McElroy had tried to play on Sunday, but fortunately for his safety, he, Rex Ryan and the rest of the Jets made the right decision on the one that truly mattered.
