It's a second Fox Sports channel that allows a Fox Sports channel such as Fox Sports Ohio to broadcast two events at the same time. One event would be on the regular Fox Sports channel and a second event would be shown on another channel (Plus) Not all cable/satellite providers will have the Plus channel. Fox Sports Ohio will be showing the Columbus Bluejackets game later in the evening which is why Marshall is not on the regular Fox Sports Ohio channel and is instead on the Fox Sports Ohio Plus channel.
