Just heard Ben Hartsock, a TE, on the radio. He had the same injury on his ring finger a few years ago and played 10 days later.
He said he thinks Murray can and will play. Once the pin is in, it's practically impossible to break it again. The only problem is the swelling and discomfort from the surgery itself, not the actual injury. Said his biggest problem will be not even the impact of the initial blow in blocking, but after that when you grab the jersey (because of course holding is basically legal now). But thinks he can compensate enough to get by.
