Randy Moss impressed in his first formal practice with the 49ers on Thursday, according to an ESPN.com report. The 35-year-old Moss even dazzled with a 55-yard touchdown catch from Alex Smith. "It's tough to tell that he missed a year of football. I certainly don't see any rust," Smith said. "He's running well, catching well. No surprise, he's a pro and already has a good understanding of the playbook."
