John Clayton is reporting that the 49ers have released linebacker Tully Banta-Cain and safety Keith Lewis. According to Clayton, their releases save the 49ers $2.275 million in cap space. Not huge releases but still interesting.
Another interesting note is that the 49ers put in a waiver claim (and failed) on QB Bruce Gradkowski. The Raiders ended up getting him. It's hard to fully determine what this kind of move means. There has been talk of Mark Sanchez by some folks, but maybe this indicates they're looking to go a little more subtle at QB.
