After Mario Manningham's 7-yard catch with 8:37 left in the third quarter, Wilkerson and Jacobs shoved each other. The two yelled at each other several yards away from where Manningham caught the pass as players from both teams rushed over to separate Jacobs and Wilkerson before things escalated.
Both Jacobs and Wilkerson were called for offsetting disqualification penalties, meaning both were done for the day with the Jets leading 7-3.
Jacobs wouldn't discuss the incident, and Wilkerson wasn't in the Jets' rookie locker room when it first opened to reporters. It's possible the players could face discipline from the NFL because of the incident.
The game, originally scheduled for Saturday night, was postponed to Monday because of Hurricane Irene. Both teams' offenses struggled to do much with their starters in, and the game took on a sloppy tone early and lasted throughout as 16 penalties were called -- seven on the Jets and nine on the Giants.
The teams meet again -- for real -- in Week 16 of the regular season on Christmas Eve in a game that might have playoff implications for both.
"I don't know if there are any tickets available to that Dec. 24 game, but I think we just sold them because that was a typical Jets-Giants slugfest right there," Ryan said. "That's two good football teams going at it. Obviously, it's a preseason game, but it is great competition, there's no doubt, and the fireworks will fly come Dec. 24, that's for sure."
