49ers' Willis, Ginn out; Seattle's Baldwin plays
Willis missed his third straight game with a hamstring injury Saturday, while Ginn was sidelined with an injured ankle. In the season opener, Ginn returned a kickoff and punt for touchdowns late in the fourth quarter of San Francisco's 33-17 win over the Seahawks.
Seattle's biggest question was Baldwin, who aggravated an ankle injury in practice this week. Baldwin went through early pregame work and was healthy enough to go. The undrafted rookie out of Stanford leads Seattle with 46 catches.
