The Buffalo Bills not only got blown out Sunday but top running back Fred Jackson is out at least three weeks and receiver David Nelson is gone for the rest of the 2012 season. Coach Chan Gailey gave the injury updates at his weekly news conference Monday, confirming an earlier report by ESPN NFL Insider Adam Schefter. An MRI exam completed on Jackson's right knee Monday revealed nothing conclusive, a source familiar with result had earlier told Schefter. It likely will be 7-10 days before a timeline is established for his return but a source estimated that the running back will miss at least a month. Jackson told Bills fans via his Twitter page that he'll be back on the field as soon as possible. He wrote: "Thanks for all the prayers all well wishes. I will get back on field ASAP! Keep Billieving in us, jus more work to do!!" Read more: http://espn.go.com/nfl/story/_/id/8362659/buffalo-bills-fred-jackson-least-three-weeks
