Leading 28–10 in the 3rd quarter, the 49ers added 14 more points. The Chargers were forced to punt after three plays on the opening drive of the second half, and Dexter Carter returned the ball 11 yards to his own 38-yard line. Young subsequently completed three consecutive passes for 53 yards on a 7-play, 62-yard drive that ended with Watters third touchdown on a 9-yard run. After a 33-yard kickoff return by Andre Coleman, the Chargers advanced to the San Francisco 33-yard line, but they turned the ball over on downs when Humphries fourth-down pass was broken up by Davis. After the turnover, Young led his team on a 10-play, 67-yard drive, aided by a 22-yard pass interference penalty against Darrien Gordon on third and 14, to score on his fifth touchdown pass, a 15-yard completion to Rice. The Chargers only highlight of the 3rd quarter was when Coleman returned the ensuing kickoff 98 yards for a touchdown. Then, wide receiver Mark Seay caught a pass for a successful two-point conversion (the first in Super Bowl history; the rule had been adopted by the NFL at the start of the season), but it only cut the deficit to 42–18.. How many points was the deficit after Mark Seay's successful two-point conversion?
