Cassel, who stepped in for Brady after the NFL's reigning MVP injured his left knee in the first quarter of Sunday's game against Kansas City, filled in for Brady on his scheduled radio appearance Monday.
``I'm not trying to be Tom Brady. I'm just trying to be Matt Cassel,'' he said the morning after leading the Patriots to a 17-10 win over the Chiefs. ``I don't know where that's going to take us.''
Brady was scheduled for an MRI on Monday amid reports that he had torn his anterior cruciate ligament, an injury that would end his season. Cassel said on WEEI that he hadn't talked to Brady, though the two had exchanged text messages.
Cassel wasn't asked about Brady's injury.
