TSN reporter Matthew Sciannitti reported a few days ago that Toronto released Horton, after trying unsuccessfully to sign him to an extension. Horton asked for his release because he was unhappy with his current role on the Argos. Sciannitti also tweeted:
And I’m hearing Horton has already been in contact w players on other teams - esp #Ticats -attempting to feel out other situations #CFL
Horton is a good player, but I can’t see signing him to replace any of our starting LB’s. Maybe sign him as a special teamer to strenthen the playoff run?
