NORMAN, Okla. (AP) Starting offensive guard Tyler Evans is getting an MRI to determine the extent of a knee injury. Coach Bob Stoops revealed after Monday’s practice that Evans was running down the field during the Sooners’ first practice of training camp Friday when he was hurt. Evans is Oklahoma’s most experienced lineman left after starting center Ben Habern gave up the sport just last week because of lingering neck and back issues. Stoops calls the loss of Habern and potentially Evans “a couple of tough breaks but we’ve still got guys in there that we really like.” Freshman lineman John Michael McGee also missed practice. Stoops says McGee was suffering from homesickness and was given the day off to decide whether he wanted to play.
