"Obviously it was a critical play," Chargers coach Norv Turner said. "You can't make those kinds of errors, and we will learn from them."
Meachem's 44-yard touchdown catch in the final minute of the half gave San Diego a 17-14 lead.
San Diego went ahead 24-14 on Ryan Mathews' 13-yard run around left end, capping a three-play drive that started when Henderson tipped a pass that Brees threw behind him, allowing Quentin Jammer to intercept it and give San Diego the ball on the New Orleans 25.
Notes: Brees set his latest passing record against the team that drafted him in 2001 and for which he played his first five seasons in the NFL before coming to New Orleans in 2006. ... The last game Brees played without throwing for a TD was Oct. 4, 2009, in a victory over the New York Jets. ... Chargers PK Nick Novak, who was filling in for the injured Nate Kaeding, made a 20-yard field goal but missed a 55-yard attempt in the second quarter. ... Saints CB Jabari Greer left the game with what team officials said was a hip injury.
