摘要： A sealing assembly for use downhole may include a plug having a first end and a second end opposite the first end. The plug may have an expandable sealing member positioned between the first end and the second end of the plug. The expandable sealing member having a run-in-hole diameter and an expanded diameter that is greater than the run-in-hole diameter. A support device may extending at least partially between a first end of the plug and the expandable sealing member. The support device may include a recess. An elastomeric material may be positioned at least partially within the recess of the support device. A cover may be positioned at least partially over the support device for reducing extrusion of the elastomeric material from within the recess of the support device in the expanded diameter.
