Write a question about the following article: The Bears traveled to San Diego's Qualcomm Stadium to start the 2007 season. They initially succeeded at containing LaDainian Tomlinson, the league's reigning MVP, but received little support from Rex Grossman and Cedric Benson. The Chargers drove into Bears' territory on their second drive, but came up empty after Alex Brown blocked a thirty-three-yard field goal. Mike Brown thwarted another Chargers' drive by intercepting Philip Rivers, which was eventually followed by a twenty-seven-yard field goal. However, Grossman drove the team into field goal position, only to throw an interception (the result of a miscue between him and Bernard Berrian) deep within Chargers' territory. However, the Bears blew their shutout in the third quarter. After a punt return mishap, the Chargers capitalized on great field position and drove into Bears' territory. Tomlinson threw a touchdown pass to Antonio Gates to cap off the drive. On the Bears' following drive, Adrian Peterson fumbled a carry, which eventually allowed Tomlinson to score a rushing touchdown. The Bears failed to cover Antonio Gates, who collected 107 yards for the afternoon. In addition to the loss, the Bears were forced to cope with the season-ending injuries to Mike Brown and Dusty Dvoracek.
