Mike Florio of Profootballtalk.com reports that Mike Tolbert's Week 1 right leg injury is "not believed to be serious." Tolbert was spotted walking without a limp in the locker room after Sunday's seven-point win over Minnesota. Early signs seemed grim, but Tolbert appears to only have a tweak or sprain. San Diego's designated red-zone back, Tolbert scored three touchdowns in Week 1 -- all inside the opposing 20-yard line. He also rushed 12 times for 35 yards and added nine receptions for 58 more yards.
