Harrison might play against Ravens

Days after he announced on Twitter that he wouldn't play against the Ravens, Steelers outside linebacker James Harrison might be ready to line up against the AFC North rival.

Harrison was cleared after missing the past four games with an eye injury and has practiced the past two days. If Harrison suits up, Lawrence Timmons would move back to his usual starting spot on the inside.

The return of Harrison would boost the Steelers' pass rush and lessen the loss of LaMarr Woodley. A source familiar with the situation told ESPN's Adam Schefter that Woodley (hamstring) isn't expected to play.

In replacing Harrison, Timmons has been steady, but not spectacular. In four games on the outside, Timmons had no sacks and two quarterback pressures.

The revolving door at linebacker continues for the Steelers this week. With Woodley likely out, Pittsburgh is expected to replace him with Jason Worilds, who has been sidelined the past four game with a quad injury.

Inside linebacker James Farrior (calf) has been limited all week in practice, too.

In other injury news for the Steelers, wide receiver Emmanuel Sanders remains in Texas, where his mother recently died, and is unlikely to play, according to the Pittsburgh Tribune-Review. Sanders, who started in place of the injured Hines Ward, would probably be replaced by Ward or Antonio Brown.

As far as the Ravens, defensive tackle Haloti Ngata (thigh) and wide receiver Lee Evans (ankle) didn't practice for the second straight day. Left guard Ben Grubbs is considered a game-time decision by offensive coordinator Cam Cameron after being limited Thursday.
