Cowboys SS Gerald Sensabaugh (knee) is in danger of missing the beginning of training camp, sources tell ESPN Dallas. Sensabaugh underwent arthroscopic surgery on his right knee recently. It's likely a minor "cleanup" procedure, but he still might have to take it easy during camp. As a returning starter armed with a new five-year contract extension, Sensabaugh doesn't need a ton of practice reps to get ready for the season.
