That's off the field.
On the field, Iupati is as tough as any one of his four offensive line 'mates.
Just consider the fourth-year left guard's four-game absence from a knee injury.
"It's getting there," said Iupati, who rejoined the gameday roster in Week 16. "Just suck it up and play. It'll feel better by Sunday."
In this way, Iupati is cut from the same cloth of his coach, Jim Harbaugh.
Asked about the single-digit, and perhaps negative, temperatures at Lambeau Field, where the 49ers open the playoffs on Sunday, Iupati said he'd simply wear a little extra clothing and "go out there and play."
Iupati, speaking after Tuesday's practice, was more concerned with the Packers, despite the fact that Green Bay's defense yielded 125 rushing yards per game during the regular season, the fourth-highest total among 16 NFC teams.
"It doesn't matter about the stats," he said. "It matters about that day, that game. You can have the worst stats, then come gameday, ball out.
"We expect a good game from them. We just have to come out, execute our plays and compete."
