General manager Martin Mayhew recently described how the Lions landed Haloti Ngata in a trade, but president Tom Lewand shared one quirky detail last week at the team's annual town hall meeting with season-ticket holders.

According to Lewand, news of the deal with the Baltimore Ravens was on Twitter before Lions coach Jim Caldwell even knew the five-time Pro Bowl defensive tackle was coming to Detroit.

"We literally finalized the trade with Baltimore; Martin Mayhew and I are on the phone in my office," Lewand said. "We hadn't even told Jim yet, and we're on the phone to (vice chairman) Bill Ford Jr., letting him know that the trade was finalized. And it pops up on Twitter as we're telling the owner we had just finalized it. We hadn't even told the head coach yet."

Tales like this are becoming the norm in the NFL with news of signings and trades popping up on Twitter, often before the parties involved even know. Last year, running back Darren Sproles found out he was being traded by the New Orleans Saints to the Philadelphia Eagles on Twitter, and other players have discovered their fate in similar ways.

Fortunately, Ngata didn't see the news second-hand; he said during his introductory news conference that Ravens coach John Harbaugh called to inform him of the deal that sent Ngata and a 2015 seventh-round pick to Detroit for 2015 fourth- and fifth-round picks.

Under Lewand and Mayhew, the Lions have done well to prevent untimely leaks, but clearly, Lewand wasn't too upset about the circumstances as he told the story to fans with a smile.
