Johnson didn't practice Wednesday due to a toe injury, Teresa Varley of the Steelers' official site reports.
The Steelers' injury report doesn't reference an ankle bruise the wideout reportedly suffered in the Week 7 win over the Titans, but it bears noting that Johnson previously managed a toe issue earlier in the season. His status will be revisited again Thursday, when Johnson should upgrade to limited or full practice participation as the Steelers prepare for Sunday's game against the Ravens.
