the fourth round of the 2008 NFL Draft. He signed a minimum salary contract over the next four years and a $500,000 signing bonus totaling $1.8 million. In his rookie season he made 13 tackles and one sack as a reserve defensive end for the Titans. Once Jeff Fisher benched veteran starter Jevon Kearse in Week 10, Hayes became the starter. St. Louis/Los Angeles Rams Hayes signed a one-year, $900,000 with the St. Louis Rams on April 6, 2012. Hayes played backup defensive end and also played defensive tackle in Rams nickel defense in 2012 and was third on team with 7 sacks. On March 12, 2013, he signed a three-year, $10.5 million contract extension that includes $5.75 million in guarantees. On March 9, 2016, Hayes re-signed with the Rams to a three-year $21 million contract. Miami Dolphins On March 9, 2017, Hayes was traded to the Miami Dolphins along with a seventh round draft pick in the 2017 NFL Draft for Miami's sixth round selection in the draft. He was placed on injured reserve on November 28, 2017, with a back injury. On March 14, 2018, Hayes signed a one-year contract extension with the Dolphins. In Week 3 of the 2018 season, Hayes suffered a torn ACL while sacking Raiders' quarterback Derek Carr, and was ruled out for the season. Mermaids and dinosaurs In December 2015, Hayes received media attention for his disbelief in dinosaurs. He claimed, "No, I don't believe dinosaurs existed. Not even a little bit." He continued, stating "I believe there is more of a chance you will find a mermaid than you will a dinosaur because we find different species in the water all the time." According to his former teammate and friend Chris Long, "He thinks archaeologists place bones underground like a parent would place Easter eggs. They just planted them. It's some large conspiracy. He does not believe that dinosaurs ever existed and he thinks that mermaids are real. I love dinosaurs, so we have a big point of contention." In a 2016 segment on HBO's Hard Knocks, it was revealed that Hayes is a firm believer in mermaids. According to head coach Jeff Fisher, "I remember him getting really excited about the potential for moving out here [from St. Louis to Los Angeles] because he knew he would be closer to mermaids here on the West Coast."
