Guys, I would highly suggest listening to The Vault podcast. I found it as a great alternative to killing my twitter account, but they tend to round up the legit sources and go in depth on everything Ravens.
I bring this up because people like Urban are part of a "handshake group" so with guys the team really want to keep but need to go on IR, they'll be added to the initial 53 and vested veterans like Urban/Seymour come back once they're moved. It's a great podcast.
