The Buffalo Bills put defensive end Jim Jeffcoat on the injured reserve list Friday, ending his season and possibly his 15-year career.
Jeffcoat has been hampered by knee problems for most of the season. He sat out four games after undergoing surgery, but has been inactive for the last three games even though he was healthy.
Jeffcoat had played in 224 consecutive games with Dallas and Buffalo before being sidelined after the Bills' game against Indianapolis on Sept. 21.
Dan Kelly said he did not know the source of the report Friday by the Buffalo News.
The newspaper said it learned that Raven Coach Ted Marchibroda, former Buffalo offensive coordinator, approached Kelly in the last two weeks about signing him for next season.
Earlier this week, Kelly, 37, said he would consider coming out of retirement on the condition that a majority of his salary be donated to Hunter's Hope Fund, a foundation named for his infant son. Hunter Kelly has Krabbe's disease, a degenerative genetic disorder that has no known cure.
Dallas Cowboy quarterback Troy Aikman walked away in frustration from the first team on Friday and began practicing with the second team. The action was shown on Friday evening sportscasts on Dallas-Fort Worth television stations. Aikman took a snap and dropped back, bumping into running back Emmitt Smith. Aikman tossed the ball to an assistant coach and walked away. Later, he refused comment on his actions.
The Tennessee Oilers put cornerback Roger Jones on injured reserve and signed defensive back George McCullough from the practice squad.
