"It says a lot," Sproles said. "I'm 33 years old. For them to give me an extra year, that says a lot. I love my teammates. I want to stay here.
"I've got some tread on the tires."
Sproles skipped all three weeks of voluntary organized team activity practices in May, but Eagles head coach Doug Pederson denied an NFL Network report that Sproles was the subject of trade talks during the NFL draft.
Sproles reported for the team's mandatory minicamp in June.
"Any time, in my opinion, that you can have a player like Darren Sproles, that you can keep him under contract for a couple of years, it makes you feel good," Pederson said. "I'm just so happy for him and his family. I'm so excited to have him here."
Acquired by the Eagles in a 2014 offseason trade with the New Orleans Saints, Sproles was named to the Pro Bowl as a return specialist the past two seasons, returning 77 punts for 952 yards with four touchdowns over that stretch.
Since joining the Eagles, Sproles has also rushed for 646 yards and nine touchdowns on 140 carries and caught 95 passes for 775 yards.
"He's got tremendous quickness and acceleration," Eagles executive vice president of football operations Howie Roseman said. "He's a mismatch in the passing game. Every time he's back on punt returns, you're thinking a big play could happen. It was a good move for us."
Originally drafted by the San Diego Chargers in 2005, Sproles currently ranks 11th all time in NFL history with 17,903 all-purpose yards.
