Who Can Replace Noah Gragson on Ovals in the Cup Series?

Noah Gragson has officially been granted his request to be released from his contract at Legacy Motor Club. That means that Legacy Motor Club has 13 races they need to find a driver for the number 42 entry.

Road course ace Mike Rockenfeller will fill in at Indianapolis and Watkins Glen, but those are road courses. Which drivers can Legacy Motor Club and Jimmie Johnson look to for that 42 car for the oval track races?
