SAN ANTONIO (AP) — Cowboys defensive end Marcus Spears will miss the rest of training camp and possibly the start of the regular season with a sprained left knee.
Spears is expected to be out four to six weeks after getting hurt late in Thursday's second practice. He has a slight ligament tear that will not require surgery.
On his Twitter account Thursday night, Spears wrote that he was good, and described the injury as a "minor setback."
Spears hasn't missed a game in five seasons since he was a first-round pick in 2005. He was selected 20th overall, nine picks after Dallas got DeMarcus Ware.
His replacement is Jason Hatcher, who has been hampered in camp by a hyperextended elbow.
