Greene left Friday's preseason game against the Saints with an apparent right leg injury, Terry McCormick of TitanInsider.com reports. Greene fumbled after a shot from safety Kenny Vaccaro and stayed down for a bit initially, but he eventually walked off the field under his own power. The 28-year-old had his right knee operated on in the offseason. Prior to exiting, Greene carried the ball nine times for 51 yards (5.7 YPC).
