Pacheco was placed on the 60-day injured list by the Tigers on Monday with a right elbow sprain, Evan Petzold of the Detroit Free Press reports.
Pacheco was dealing with an elbow injury when the Tigers claimed him off waivers from the Cardinals earlier this month and now he'll miss at least the first couple months of the season. The specifics on the 24-year-old's injury aren't clear at this time.
