The Hamilton Tiger-Cats announced on Tuesday that after discussing all options with the players involved, Canadian linebacker Rob Hitchcock and Canadian wide receiver Mike Morreale have chosen to be released by the team.
We have offered both Mike and Rob an opportunity to remain with our organization and they have indicated that they would like some time to reflect on the offer.”
