One holdout defensive end is under contract, but there is still ground to gain in negotiations between the Cincinnati Bengals and Trey Hendrickson. Hendrickson, the NFL leader in sacks last season with 17.5, is training in Florida while Cincinnati gets ready for the regular season. The Bengals have made progress toward an agreement with the 30-year-old, but ESPN reported Monday the hangup over the amount of guaranteed money in the deal is significant. NFL reporter Adam Schefter said during an interview on “The Pat McAfee Show” on Monday the two sides are OK with the length and total amount in the new contract.
