Following two consecutive wins at Giants Stadium, the Bears were to finish a three-game road trip at Gillette Stadium against the New England Patriots. Similar to the week nine confrontation with the Miami Dolphins, turnovers contributed to the Bears' 17-13 loss against the Patriots.  The opening two quarters were a story of turnovers in a Rex Grossman interception by Asante Samuel, a Benjamin Watson catch knocked into the hands of Charles Tillman, a blocked Bears field goal attempt, and fumbles by Laurence Maroney and Grossman.   The third quarter saw a bizarre sequence of turnovers - first fumbles by both Watson and Reche Caldwell on the same play, followed by another Samuel interception of Grossman, and finally a second Tillman interception of Brady.   Through three quarters the game was tied 10-10 before a drive where Brady faked out Brian Urlacher on a nine-yard run ended in a two-yard score to Watson.  Turnovers then ended the game, with a Corey Dillon fumble followed by Samuel's third interception of Grossman.  Samuel's three picks tied Roland James in Patriots history for three interceptions in one game.
