A key face is missing as the Cincinnati Bengals open training camp on Tuesday.

Star edge rusher Trey Hendrickson did not report as he seeks a new contract, ESPN’s Adam Schefter reported.

The 30-year-old posted a picture to Instagram with a location tag of Florida, where he is based during the off-season.

Hendrickson was an All-Pro selection last season after he led the league with 17 1/2 sacks. He did not attend last month’s mandatory minicamp, but did make an appearance during an off-season workout in May to vent his frustrations about negotiations.

Hendrickson is seeking a long-term extension with an amount of guaranteed money that matches what the league’s top pass rushers are earning. He is scheduled to earn $15.8 million in base salary and has a cap number of $18.7 million.

“He’s earned a raise and an extension, and we’ll continue to see if we can come together on something,” Bengals director of player personnel Duke Tobin said. “Having good players is a good problem to have, and we’ve got a lot of good players, and we’ve got a lot of highly paid players, and fitting it together is what we’re working for.”
