The Bears were unable to replicate their success in the 2007 season, and finished last in the NFC North. In the middle of the season, Urlacher admitted that he had been suffering from an arthritic back, but later claimed the ailment was not serious. Nevertheless, he finished the season on a high note, registering five interceptions, five sacks, one fumble recovery, 123 tackles, and a defensive touchdown. Following the season's conclusion, Urlacher received minor neck surgery to treat his arthritic back. During the offseason, Urlacher revised his contract with the Bears, who granted him a $6 million signing bonus with a $1 million increase in salary each of the next four years.
