Thielen was limited at practice Wednesday due to an ankle injury, Chris Tomasson of the St. Paul Pioneer Press reports.
Thielen didn't initially appear on the Vikings' first practice report of the week that was submitted Tuesday, so his inclusion Wednesday hints that he may have suffered an in-practice setback. The wideout's status will be revisited again Thursday, at which time it'll be known whether he approaches Saturday's playoff game against the 49ers listed as questionable or without an injury designation entirely.
