The Baltimore Ravens have won 16 straight preseason games.
The Ravens topped the Philadelphia Eagles 26-15 in a lightning-shortened game at Lincoln Financial Field on Thursday night.
The winning streak is the longest such streak in the NFL in at least 25 years. The Ravens haven't lost in the preseason since Sept. 3, 2015.
"I don't know how significant it is," John Harbaugh said. "I think it's significant in a sense that I think our coaches do a great job of coaching in training camp. We develop players really well."
