Robert Geathers done for season

CINCINNATI -- The Bengals made a series of roster moves Wednesday afternoon that included placing 10-year veteran Robert Geathers on injured reserve. The defensive end suffered a season-ending elbow injury against Pittsburgh on Monday night.

In addition to placing Geathers on IR, the Bengals re-signed free agent safety Jeromy Miles after waiving him just before Monday's game. Miles cleared waivers this week.

The Bengals also signed free agent Curtis Marsh. The third-year player from Utah State was a third-round pick by Philadelphia in 2011. Across the 2011-12 seasons, he played in 22 games, including 15 last season, when he had 10 special teams tackles and six on defense. He was on the Eagles' preseason roster this year but missed time because of a fractured hand. He was waived by the Eagles on Sept. 5.

Marsh was at practice Wednesday afternoon. He likely takes a post vacated by linebacker J.K. Schaffer, a 2013 offseason signee who was waived by the Bengals after having been moved off the practice squad to the 53-man roster just before Monday's game. A Cincinnati native and University of Cincinnati product, Schaffer appeared in the 20-10 victory over the Steelers. It is expected that Schaffer will be returned to the practice squad Thursday.

On Tuesday, the Bengals terminated the contract of veteran running back Bernard Scott.
