San Francisco 49ers head coach Jim Harbaugh, left, is greeted by his brother-in-law John Feuerborn, right, at the end of their NFL football practice in Santa Clara, Calif., Friday, Jan. 20, 2012. The 49ers are scheduled to host the New York Giants in the NFC Championship game on Sunday, Jan. 22.

SANTA CLARA, Calif. — Offensive lineman Adam Snyder and 49ers special teams standout Blake Costanzo sat side by side in outdoor ice tubs, each sporting a beanie to keep his head warm while playing with their respective cellphones.

Fullback Bruce Miller considered it "torture."

Jim Harbaugh asked for rain this week, and he got it — just not enough to satisfy the San Francisco coach who wanted his players to practice on a soggy field ahead of Sunday's NFC championship game.

More rain is in the forecast in the Bay Area, and the 49ers pulled out the cold-weather clothing before working out in windy, chilly conditions Friday.

Harbaugh expects the field at Candlestick Park to be in good shape considering the grass was replaced before the Monday Night game Dec. 19.
