ALAMEDA -- While running back Darren McFadden (foot) was again not on the field at the start of practice Friday, placekicker Sebastian Janikowski (hamstring) had a helmet on but had yet to kick before the media window closed.
There is little doubt that McFadden will sit out Sunday's sold-out home game against Denver but Janikowski is a more interesting and delicate case. Coach Hue Jackson acknowledged Thursday he would have a kicker on speed-dial in case Janikowski cannot go again. Dave Rayner was on the roster for the Raiders' 28-0 loss to Kansas City on Oct. 23. He had the opening kickoff and never stepped on the field again.
Meanwhile, free safety Michael Huff (ankle) and strong safety Tyvon Branch switched jersey at the beginning of practice.
