Crosby made both his field-goal attempts, a 28-yarder followed by a 34-yarder just before halftime, to give him the league record for most consecutive field goals made in postseason play with 20.
David Akers previously held the record of 19.
Crosby's kicks Saturday night allowed the Packers to enter halftime trailing the Arizona Cardinals, 7-6. The second field goal capped a 17-play, 71-yard drive that spanned 6 minutes and 55 seconds, the Packers' second-longest of the season.
The Packers went on to lose in overtime, 26-20.
Crosby said he didn't know he was in line for the record until midweek, when told by someone on the Packers' staff.
"Someone told me [I'm at] 18. That's pretty cool," Crosby said during the week. "Just need to make the next one."
His last miss was Jan. 15, 2011, at Atlanta in an NFC divisional playoff win on the Packers' road to Super Bowl XLV.
