Subtract another cornerback from the competition. After terminating the contract of probable starter Aaron Berry on Monday, the Lions announced that rookie cornerback Chris Greenwood, their fifth-round pick out of Albion, will start the season on the physically unable to perform list. The Lions said Greenwood tore a muscle in his lower abdomen during an OTA practice in May. The injury required surgery. "It's definitely been frustrating just because I haven't been able to show what I can do," Greenwood said in a story on the team's website. "I haven't had the opportunity outside of a couple days that I practiced. It's something people go through sometimes and I'm just trying to bounce back." Source: Detroit News
