The Bengals placed McPherson on injured reserve Wednesday with a right groin injury.
McPherson will thus miss at least four games, meaning that the soonest he'll be eligible to return from IR is Week 18 against the Steelers. Heading into Monday's game against the Cowboys, the Bengals sit on a 4-8 record for the season. If the team is eliminated from playoff contention by the time Week 18 rolls around, the Bengals may just decide to keep McPherson on IR for the duration of the season. The Bengals signed Cade York to their practice squad Wednesday and are likely to elevate him ahead of Monday's game to replace McPherson, who converted 16 of 22 field-goal attempts and 37 of 38 extra-point tries through Cincinnati's first 12 games.
