GLENDALE, Ariz. — As ugly as it started, it ended even uglier for the 49ers, who lost their sixth straight game Sunday and had a win slip from their grasp in the final minute.
The 49ers blew a 15-3, fourth-quarter lead against the the league’s worst offense as the Arizona Cardinals rallied for an 18-15 victory.
It marked the fourth straight season the 49ers have been swept in the home-and-away series by the Cardinals. Each team entered with 1-6 records, and they looked like lousy, one-win teams for much of Sunday’s game.
Rookie quarterback Josh Rosen threw a pair of fourth-quarter touchdown passes in the Cardinals’ comeback, capped by a 13-yard pass with 34 seconds remaining to Christian Kirk, who slipped past Tyvis Powell and took a hard shot from Jimmie Ward under the goal posts.
