Former Fort Dorchester star Carlos Dunlap agreed to a lucrative six-year contract extension with the Cincinnati Bengals, while former South Carolina standout Ace Sanders signed his rookie contract with the Jacksonville Jaguars on Monday.

Dunlap, a 6-6, 280-pound defensive end who played at Florida, reached an extension that is believed to be worth $40 million. The deal is expected to be officially announced Tuesday.

Dunlap has made just two starts over his first three seasons, but had 9½ sacks a year ago in just 12 games. In 38 career games, he has 87 tackles, 20 sacks, four forced fumbles and one interception, which he returned for a touchdown during his rookie season. The 24-year-old, who was a second-round pick in 2010, also returned a fumble recovery for a touchdown.

Sanders, a fourth-round pick in April’s NFL draft, agreed to terms last week before signing Monday. A receiver/punt returner, Sanders was the 101st overall selection.

The 5-7 speedster finished his college career with 99 receptions for 1,230 yards and 13 touchdowns. He also averaged 11.2 yards on 53 punt returns and scored three touchdowns. He had a career-high 45 catches for 531 yards and nine touchdowns as a junior last season and ranked fourth nationally in punt returns, averaging 15.3 yards.

“I can’t wait to get started again later this month,” Sanders said. “I’m looking forward to getting back to work and finding my role in the passing game and as a returner.”
