Former Bears safety Chris Harris has enjoyed great popularity on Twitter and other social media, so it seemed only fitting his retirement announcement came via tweet on Saturday night. Harris had 16 interceptions and forced 14 fumbles in his career. He spent the 2005, 2006, 2010 and 2011 seasons with the Bears and also spent time with the Lions, Panthers and last season, with the Jaguars, appearing in just five games. "After 8 awesome yrs in the NFL I'm deciding to retire," he tweeted to his nearly 45,000 followers. "This was one heck of a ride and I've been extremely blessed to have played this game." Harris, a sixth-round draft pick by the Bears, had his most productive season in 2007 with the Panthers, when he forced eight fumbles.
