The Packers improved to a 9-3 record by defeating the New England Patriots 26-21, despite going 0 for 4 in the red zone. It was the first matchup between Rodgers and Brady, as Rodgers missed the 2010 matchup at Gillette Stadium with a concussion. Aaron Rodgers continued a streak of passes at home without an interception: 360 passes including 31 touchdown passes. The Patriots were only behind 16-14 with a minute left in the first half, but a 45-yard touchdown pass to Jordy Nelson gave Green Bay a 9-point halftime lead. A scoreless third quarter, and no red-zone touchdowns for the entire game for the Packers, gave New England a chance for victory. The Patriots scored again to make it only a two-point deficit, but another Green Bay field goal and stout fourth-quarter defense gave the Packers victory over a strong Patriots squad.
Question: How many points did Green Bay have at halftime?
Answer: 23
