SANTA CLARA, Calif. - Patrick Willis, who missed the 49ers' loss in Denver two weeks ago with a big toe injury, will be a game-time decision Sunday when San Francisco hosts the St. Louis Rams.

Willis, third on the team with 49 tackles, says Friday he still feels pain but is getting better every day.

While Willis does not suffer from turf toe, a severe injury that sidelined cornerback Tramaine Brock for five games and who remains questionable this week, the injury does affect everything Willis every time he takes a step.

Rookie linebacker Chris Borland started in place of Willis against the Broncos and will fill the void again should Willis be unable to go.
