Raiders' DE Upshaw appeals fine for coach confrontation

ALAMEDA, Calif. (AP) -- Oakland defensive end Regan Upshaw was fined $87,000 by coach Bill Callahan for a confrontation with offensive line coach Aaron Kromer two weeks ago, CBS Sports reported Sunday.
Upshaw then filed a grievance against the Raiders on Thursday as an appeal to the fine, which amounted to about a week's pay, CBS reported on "The NFL Today" and SportsLine.com.
Upshaw, the team's sacks leader last year who's recovering from knee surgery, was activated from the "physically unable to perform" list to the 53-man roster Wednesday.
He was not active for the Raiders' 41-20 win Sunday at Arizona, but he did travel with the team.
When asked about the incident while leaving the field, Upshaw said he had no comment.
Callahan acknowledged that something had happened, however.
"That's a discipline issue," Callahan said. "And discipline-wise, all that stays in-house. That's my policy. It's an in-house and family matter."
Telephone calls to the players' union were not returned.
Upshaw tore the anterior cruciate ligament in his right knee during the team's final minicamp in June and was thought to be done for the season.
Yet the Raiders did not place him on the injured reserve -- which would have forced him to remain sidelined all season -- leaving open the possibility he would be healthy enough to return.
