Dierrias J. Humphries Jr. (born December 28, 1993) is an American football offensive tackle for the Arizona Cardinals of the National Football League (NFL). He played college football at Florida. Humphries won the 2011 Anthony Muñoz Award, awarded to the best lineman in high school football. A native of Charlotte, North Carolina, Humphries attended Mallard Creek High School, where he was a three-sport athlete in football, basketball, and track. He was an All-American offensive lineman, clearing the way for 2,000-yard rusher Jela Duncan, and helping protect quarterback Marquise Williams. Humphries started from his freshman season and did not allow a sack over the final three years of his prep career. In 2011, Humphries helped Mallard Creek to a 13–1 record and berth in the NCHSAA Class 4AA State Semifinals, where they were upset 41–27 by Greensboro (NC) Page. In track & field, Humphries competed in the shot put (top-throw of 48 ft 9 in, or 15.25 m) and the discus (105 ft 3 in, or 32.15 m). Regarded as a five-star recruit by Rivals.com, Humphries was ranked as the No. 1 offensive tackle prospect of his class, ahead of No. 2 prospect Zach Banner. Rivals compared him to D'Brickashaw Ferguson. Head Coach Bruce Arians nicknamed him "knee-deep", explaining that you need to keep "A knee in his ass every day" to keep him motivated. He started his rookie season as the Cardinals' third right tackle on their depth chart, behind veterans Earl Watford and Bobby Massie. During his rookie season, he was inactive for all 16 regular season games and both postseason contests. He was the only first round draft pick in 2015 to be inactive the entire season. To begin his second season with the Cardinals, Humphries was named the starting right tackle to begin the regular season. He had his professional debut and first career start in the Arizona Cardinals' season opening 21-23 loss to the New England Patriots. On November 27, 2016, he made his first career start at left tackle in a 19-38 loss to the Atlanta Falcons. Starting left tackle Jared Veldheer suffered a torn triceps a few games prior and Humphries replaced the struggling John Wetzel who was in place of Veldheer.[13] On December 11, 2016, Humphries suffered a concussion during the first half of a Week 14 23-26 loss to the Miami Dolphins. Humphries entered the 2017 season as the Cardinals' starting left tackle. He suffered an MCL sprain in Week 1 and missed the next four games. He returned in Week 6 and started the next four games at left tackle. However in Week 10 on Thursday Night Football, Humphries left the game with a knee injury. He was later diagnosed with a dislocated knee cap and an MCL injury and was ruled out for the season. On April 24, 2018, the Cardinals picked up the fifth-year option on Humphries' contract. He started the first nine games at left tackle before suffering a knee injury in Week 10.
