Shaquelle Evans

Three players on the Jets suffered concussions in Friday’s preseason game against the Falcons.

Coach Todd Bowles said after the game that wide receiver Jeremy Kerley, running back Daryl Richardson and safety Durell Eskridge all had concussions.

The Jets’ concussions, as well as the concussion suffered by Robert Griffin III on Thursday, bring back into focus a common concern in the NFL: Players are putting their health at risk in meaningless preseason games. Owners and players alike have shown interest in the possibility of shortening the preseason, but they can’t come to an agreement on how to go about doing that, and whether the regular season should be lengthened to compensate for the lost preseason games.

Jets wide receiver Shaquelle Evans also suffered a back injury, while offensive tackle Ben Ijalana suffered a knee injury and defensive back Dashaun Phillips suffered a rib injury.
