Buffalo Bills coach Chan Gailey confirmed this afternoon receiver David Nelson is done for the season and running back Fred Jackson will be out "a few weeks."
The key members of Buffalo's offense suffered right knee injuries in Sunday's loss to the New York Jets at the Meadowlands.
The nature of lateral collateral ligament injuries leaves some speculation for how long Jackson will be out. Gailey said they'll be without him at least until October.
"It's not going to be three [weeks], but I don't think it's going to be eight," Gailey said. "It's probably somewhere there in between. Hopefully, sooner.
"The prognosis is decent."
Gailey called Jackson's outlook "decent" because the way Jackson went down looked like a potential season-ender. Jets safety LaRon Landry hit Jackson in the left leg, and Jackson twisted his right knee while tumbling awkwardly to the turf.
The Bills will have a roster spot available with Nelson headed to injured reserve. Gailey said the Bills would consider adding a tailback because there are only two healthy ones on the roster now: C.J. Spiller and Tashard Choice.
At receiver,the Bills have Brad Smith, who didn't play a snap Sunday, and rookie T.J. Graham, who was deactivated Sunday. Gailey indicated Graham will be on the field for the home opener against the Kansas City Chiefs to help fill Nelson's void.
"T.J.'s going to get a shot now to show what he's got," Gailey said.
