I tuned into the 49ers-Broncos preseason game to get a glimpse of Knowshon Moreno's first NFL action. He looked good on his first couple of carries and still had his run back to the huddle after getting tackled. But after throwing a block on the 3rd Kyle Orton interception of the night (it was only the 2nd quarter), he left with a leg injury. I guess he has found out the tough part of life in the NFL pretty quick. Earl also made me aware that Knowshon is appearing in a series of Reebok ads about life as a rookie at training camp and after seeing them I must say they are both pretty fun. Check out the videos below.
