Sources inside the Jets locker room tell us backup linebacker IK Enemkpali -- the puncher -- organized a youth football camp and charity in Texas last month. He invited Geno to attend -- even put his face on the flyer -- but for some reason Geno didn't make it.
We're told IK stepped to Geno to talk about it on Tuesday, but Geno told him to back off because he wasn't going to discuss it at that moment. Geno turned away, but IK stood his ground ... and socked Geno in the jaw.
