Cleveland Browns running back Peyton Hillis is not practicing because of an unspecified injury. Hillis has 252 carries and 59 catches in his first season with the Browns, who acquired him in a trade with Denver. Coach Eric Mangini doesn't believe Hillis, who has 1,129 rushing yards, is wearing down and said the workhorse back's injury "is nothing that I'm that concerned about." Source: cbssports.com
