Sounds like the roller cover. Take the bottom drawers out of the dresser and see if it is exposed. If not, see if the bottom of the dresser under the drawers is made to be removed.
The roller cover is a vacuum formed part that Monaco makes in-house. Don't know anywhere you can get one except from Monaco. If that is what was crushed, you may find a local company that can make vacu-formed products to make one or you.
