Newberry's agent, Doug Hendrickson, told The Associated Press on Tuesday that the former longtime starting center for the San Francisco 49ers hurt his left knee. Hendrickson said Newberry's knee "just kind of went out on him recently when he was pushing hard to get ready for training camp."
At age of 33, Newberry was expected to provide depth at guard and center in the Falcons. He used to start three games the San Diego Chargers last season. Before that while he was playing for the Oakland Raiders in 2007, he started each of his 14 games.
