He is getting killed on espn this morning. If he's on the roster next week he will be lucky.
Edit:
Maybe not. Here is a quote from teh Eagles coach:
"Marvin just needs to execute better, but that's football. He had his chances, and stayed competitive until the ball was out of bounds, but things just didn't up going his way last night. Just one less step back and the ball wouldn't have nearly sodomized him, but football is game of inches. That wasn't a dog crap block, just one of those ebbs and flows of football. Marvin blocking on the wing on punts gives us the best chance to win. After all, he did catch the winning pass in a college game in 2009."
