Small tear in PHY-HP driver, please help

I was installing my PHY-HP drivers into the cabinet i designed, and poked a small tear/hole in the paper driver, near where it meets the surround. It is 3-4mm in diameter. I was extremely careful, yet I feel like such an idiot even posting this. Alas, the screws which clamp the driver to the wood are slotted heads rather than Philips heads, and the screwdriver slipped and jammed into the driver. I could vent about slotted heads, as I don't understand why their still used, but that would do little to repair the driver.

Any thoughts on how to repair this, or how big of a deal it is? Thank you sincerely.
