Detroit Lions receivers coach Shawn Jefferson was seen yelling at offensive coordinator Scott Linehan during the fourth quarter of the team's 24-20 loss to the Packers.

"I'd rather not go into it," Jim Schwartz said. "Everybody was disappointed not to be able to score a touchdown on that last drive."

Schwartz believes Detroit's lack of execution is to blame, not Linehan.

"We weren't clicking," Schwartz said. "We had a couple of times where we misfired on passes. A couple of times we had chances and dropped ball. A couple of times we had miscommunication and route adjustment. We didn't do a good enough job. We didn't do a good enough job pass protecting either.

"So yeah, our passing game definitely wasn't clicking. Give some credit to the Packers. They played a lot of tight match coverage."
