McCoy sustained a concussion on the hit but continued to play. The league and players association representatives are investigating the Browns' handling of the injury.
Harrison's hit on McCoy marked the linebacker's fifth illegal hit on a quarterback in the last three seasons. The four-time Pro Bowler has also been fined on two other occasions for unnecessary roughness over the same period.
Barring a successful appeal, Harrison will miss Pittsburgh's game at San Francisco on Monday night.
In other news, Steelers quarterback Ben Roethlisberger is questionable for Monday's game due to a sprained left ankle.
Coach Mike Tomlin said yesterday that Roethlisberger is "day-to-day" but is working "tirelessly" to be on the field against the 49ers.
Roethlisberger was injured in Thursday's game.
Arizona quarterback Kevin Kolb said in his weekly radio interview that his concussion "symptoms are pretty good," and he hopes to be able to be cleared for this weekend's game against Cleveland. He was injured in Sunday's win over San Francisco.
* Dallas owner/general manager Jerry Jones said that head coach Jason Garrett's job is safe no matter how the Cowboys finish the season. "It's really not even something worth discussion," Jones told ESPN.
* Washington signed tight end Richard Quinn and placed nose tackle Chris Baker (quad) on injured reserve. Quinn was a second-round draft pick from North Carolina by Denver in 2009. He played in 29 games, with four starts, in two seasons with the Broncos before being released this preseason.
* Buffalo signed offensive tackle Erik Pears to a contract extension. Terms of the deal were not released. Pears, a 7-year veteran, is in his first full season with the Bills.
* Kansas City general manager Scott Pioli said he accepts responsibility for the lack of depth in the organization that has resulted in the lackluster performance on the field. Pioli fired coach Todd Haley on Monday with the team in the midst of a 5-8 season. Chiefs chairman Clark Hunt said he is confident Pioli can turn the franchise around.
* The New York Jets signed veteran safety Gerald Alexander, adding depth to the position 2 days after Jim Leonhard was lost for the season because of a knee injury. Alexander, a former second-round pick of Detroit in 2007, was waived by Miami last month after spending last season with Carolina and Jacksonville.
