Vernon Davis took no snaps on the perimeter and just one from the slot during San Francisco 49ers practice Tuesday.The subject is of interest after Davis, a career tight end, suggested he would be working with wide receivers. The truth is that Davis will remain a tight end even if he does line up in the slot or outside the numbers a little more frequently.Davis has averaged 19.0 yards per reception, tops among tight ends over the past two regular seasons and playoffs, when lined up in the slot or outside the yard-line numbers, according to Doug Clawson of ESPN Stats & Information.
