Right now the Giants preseason game is on WFAN AM and FM and WCBS-FM. The Met game started at 4 PM and didn't finish until after 7 PM, the starting time of the Giant game. I assume that the Giant radio contract still states that their games must be on a CBS owned station. Likely in September when the regular football season begins, the Met game will move to WBBR so the Giants would be heard on WFAN.
