Lions quarterback Matthew Stafford had surgery on his throwing shoulder Friday. Detroit expects the former No. 1 draft pick to be back in time for training camp after playing only three games last season. "After Matt hurt his shoulder in the [Nov. 7] game he was examined by both our medical staff and Dr. Andrews. There was a consensus at the time to proceed with a rehabilitation program and not to have surgery," coach Jim Schwartz said. "After Matt's most recent visit to Dr. Andrews, it was determined by Dr. Andrews that Matt's healing process could be enhanced by undergoing surgery at this time. ... We have full confidence that Matt will be 100 percent before the start of training camp."
