Bears open preseason in San Diego

The Chicago Bears announced their 2010 preseason opponents on Wednesday, and the four-game slate features home match-ups versus the Oakland Raiders and Arizona Cardinals, and road dates against the San Diego Chargers and Cleveland Browns.

The Bears' preseason opener, scheduled for the weekend of August 12-15, will be against the Chargers at Qualcomm Stadium. The next two games will be held at Soldier Field, versus the Raiders and Cardinals, before the preseason finale in Cleveland.

This marks the seventh consecutive year the Bears and Browns will square off during the preseason.

Exact times and dates for these contests have yet to be released.

NFL regular-season schedules are expected to be revealed in the middle of April, but the Bears already know who their opponents will be in the fall. In addition to their normal home and away games versus division rival Green Bay Packers, Minnesota Vikings and Detroit Lions; the Bears will play host to the New England Patriots, New York Jets, Washington Redskins, Philadelphia Eagles and Seattle Seahawks. They'll travel to the Miami Dolphins, Buffalo Bills, Carolina Panthers, New York Giants and Dallas Cowboys.
