Titans RB Chris Johnson had 69 yards (2008) and 57 yards (2009) in his two games against Pittsburgh. The Steelers have had the AFC's best rush defense during that span, with only Ray Rice of Baltimore gaining more than 100 yards against them in their last 35 regular season games. Rice ran for 141 yards during a 23-20 Ravens loss on Dec. 27.
Johnson has had 12 consecutive 100-yard games dating to last season, and the Steelers aren't eager to be the victims of No. 13.
"He's definitely putting himself up there to be talked about as the best in the game, if he keeps this up,'' Steelers linebacker James Farrior said.
The Steelers rarely allow any back to gain that kind of yardage. They have yielded only four 100-yard games over the last five seasons-plus, to the Colts' Edgerrin James (124 yards in 2005), the Jaguars' Fred Taylor (147 in 2007), the Jets' Thomas Jones (117 in 2007) and Rice.
"We're going to be extra motivated this week,'' Farrior said.
