Floyd has 13 catches for 227 yards and a touchdown in three games this season. The 6-foot-5, 225-pound former Wyoming player has 190 receptions for 3,397 yards and 21 touchdowns in eight NFL seasons.
"I guess all these years of hard work have paid off," Floyd said in an interview posted on the team's website. "They took great care of me, and now I get to start and finish my career as a Charger. That's something I always dreamed about."
Also, left tackle Jared Gaither practiced for the first time since injuring his back July 28, and hopes to play Sunday in Kansas City.
"That's the goal," Gaither said. "This was a big day, a major hurdle to my return. It felt good to be out there, and I'm going to keep on working and try to help this team in a game as soon as humanly possible."
That might come the following week in New Orleans.
"We'll see how the week goes," Chargers coach Norv Turner said. "He did well today, but he has some work to do to get back in the swing of things."
