Lions quarterback Matt Stafford continues to work his way back into shape after undergoing surgery on his throwing shoulder. "Feelin good after throwing a lot yesterday," Stafford tweeted Saturday. The Lions can receive reports on Stafford's progress, but they aren't permitting to make contact with him during the lockout. "There's nothing he's had injury-wise his first two years that is going to affect him going forward," Lions coach Jim Schwartz said this week. "He knows that, we all know that. We (just) need to keep him on the field."
