EAST RUTHERFORD, N.J. - Buffalo Bills fans are holding their breath about running back Fred Jackson's right knee, but wide receiver David Nelson's injury might hurt the team more.
Both players suffered right knee injuries in the New York Jets' humbling, 48-28 victory Sunday at the Meadowlands.
Each walked to the locker room under his own power, but Nelson needed a golf cart to transport him from the locker room to the team bus.
"Fred doesn't look as bad as David," Bills coach Chan Gailey said. "We don't know how bad David is, but it doesn't look good right now."
Jackson's knee is believed to be sprained. The fear with Nelson is that his season is over.
They will undergo MRIs today and be reevaluated. Neither spoke to reporters after the game.
Jackson got hurt in the second quarter. He ran off right tackle for a 7-yard gain before Jets safety LaRon Landry cut him down at the sideline. Landry hit Jackson's left leg, but his right knee twisted on the way down.
Jackson cried in frustration as he paced on the sideline for several minutes. He jogged in place and tried to make some cuts with medical professionals observing. He then went to the locker room and didn't return.
C.J. Spiller was terrific in Jackson's absence, rushing 14 times for 169 yards and a touchdown.
Finding a replacement for Nelson will be tougher. He went down in the fourth quarter, apparently while making a cut away from the play.
Nelson was Buffalo's second-leading receiver last year with 61 catches for 658 yards and five touchdowns.
The Bills kept only four full-time receivers at the end of preseason.
They added special-teamer Ruvell Martin last week when they placed cornerback Ron Brooks on injured reserve.
Martin dressed Sunday, while third-round draft choice T.J. Graham was a healthy scratch.
If the Bills want to add another receiver, then they can promote Marcus Easley from the practice squad. University at Buffalo star Naaman Roosevelt is another option.
Some notable free agents include Jabar Gaffney, Plaxico Burress, Deion Branch and Mike Sims-Walker.
Former Bills defenders Aaron Maybin and Ellis Lankster were among the Jets' captains at the opening coin toss.
When players face their former teams, Jets coach Rex Ryan's policy is to name them captains.
Lankster had three tackles. He stopped Spiller for a loss of 5 yards on a screen pass.
The coin flip was the about the extent of Maybin's activity. He didn't record a tackle on defense or special teams. But he was satisfied with the victory over the team that cut him in August 2011.
"Yes, it feels good. I'll say that," Maybin said with a sheepish grin. "Obviously, we would have liked to have finished the game on a stronger note on defense. We kind of gave up some big plays toward the end in the second half . but to see all three phases of the game come together and put together a winning effort is great."
Here's something you don't see every day: The Bills had one special-teams tackle.
The Bills kicked off only four times, and specialist John Potter recorded three touchbacks.
Known for his big leg, Potter's opening kickoff was returned 24 yards by Joe McKnight. Bills linebacker Chris White made the tackle at about 1:02 p.m., and that was that for special teams.
Brian Moorman punted twice. On his first attempt, Jeremy Kerley returned it 68 yards for a touchdown. His second punt went out of bounds.
