The spread is a reversal of their Week 4 matchup, when Pittsburgh was a three-point home favorite. The Ravens won handily then, 26-14, but have since fallen to third place in the AFC North, behind the division-leading Steelers (4-2-1) and Cincinnati Bengals (5-3).
If the line holds, Sunday’s game would be the fourth straight in which the Ravens (4-4) were favored by about a field goal, and the fifth overall with a spread of three points or fewer.
The Ravens are 4-3 overall and 6-1 against the spread in their past seven meetings against the Steelers, according to CBS Sports. But Pittsburgh has won three straight games entering Sunday and is 4-0 in its past four games as a road underdog.
The over-under for the game is 47½ points.
