Bengals LCB Nate Clements is still nursing an abdominal strain. Clements sat out May OTAs with the ailment and now he's watching training camp from the sidelines. Still, it's possible the Bengals are just playing it safe after first-round CB Dre Kirkpatrick went down with a knee injury earlier this week. "With these type of injuries you have to take your time," Clements said. "It can keep lingering on and that is not one of those things we want to rush."
