During Week 4 against the Indianapolis Colts, Burfict made a helmet-to-helmet hit on Jack Doyle, and was ejected from the game. The next day, the NFL suspended Burfict for the rest of the 2019 season without pay. In a letter to Burfict notifying him of the suspension, NFL vice president of operations and chief disciplinarian Jon Runyan told Burfict that he had continued to “flagrantly abuse” player safety rules despite numerous warnings from the league. This became the longest suspension for on-field misconduct in modern NFL history, more than doubling the five-game suspension mandated to Albert Haynesworth in 2006. Burfict appealed his suspension, but on October 9, the NFL upheld the suspension. Three days earlier, on October 6, the NFL notified Burfict that they had found another illegal hit during the Week 4 game. During the second half, he also made a helmet-to-helmet hit against Colts running back Nyheim Hines, although no penalty was called during that time. He was reinstated on December 30, 2019. Since then, Burfict indicated his intent to continue playing in the NFL; he became a free agent in 2020 at the conclusion of his one-year contract with the Raiders.

Burfict attended Centennial High School in Corona, California, where he was part of an undefeated Huskies team that won a CIF title, a state championship with the help of quarterback Taylor Martinez, and was ranked second in the nation by USA Today in 2008. That year, Burfict led the Huskies with 159 tackles, two quarterback sacks, two interceptions and two fumble recoveries. Burfict participated in the US Army All-American Bowl and was the third-leading tackler for the West team. He also earned numerous All-American honors, including Parade.

He played in the 2009 U.S. Army All-American Bowl. Considered a five-star recruit by Rivals.com and Scout.com, Burfict was listed as the No. 1 inside linebacker prospect in the nation.

On October 6, 2010, Burfict was benched by Arizona State head coach Dennis Erickson. The reason given was Burfict’s unusually high number of personal foul penalties. In a game against Stanford, Burfict was called for grabbing the facemask of Doug Baldwin, and—after complaining to the referee—charged with a personal foul for unsportsmanlike conduct that gave Stanford a first down at the ASU 7. Two plays later, Stanford scored what turned out to be the winning touchdown.

With senior cornerback Omar Bolden lost for the season to a knee injury, Burfict was expected to take over as the leader of the Sun Devils defense in 2011, but eventually had a rather inconsistent junior season. Burfict decided to forgo his senior year at Arizona State to pursue a career in the NFL.

Prior to his junior season, Burfict was regarded as one of the best linebackers available in the 2012 NFL Draft and was projected to be a first round pick by NFL draft experts. Problems on and off the field at Arizona State, however, caused his draft stock to plummet immensely. In October 2011, Sports Illustrated′s Tony Pauline ranked him as 20th best prospect on his midseason draft board, but noted that he has been “a loose cannon on and off the field, which has raised red flags.” On January 3, 2012, Burfict announced his decision to forgo his senior season and enter the 2012 NFL Draft. Prior to the NFL Combine, Burfict was ranked as the fifth best linebacker prospect in the draft by NFL analyst Mike Mayock. He attended the NFL Scouting Combine and performed the majority of drills, but skipped the short shuttle and three-cone drills after injuring his hamstring on his second 40-yard dash attempt.

His overall performance was described as “disappointing” due to a 5.09 sec in the 40-yard dash, which was the slowest among all linebackers. Burfict also finished last among linebackers in the broad jump and finished second to last among linebackers in the vertical jump. On March 16, 2012, Burfict attended Arizona State’s pro day and performed the bench press (16 reps), vertical jump (30”), short shuttle (4.56s), and three-cone drill (7.51s). Burfict described his overall pro day performance as “average”. On April 25, 2012, it was reported by Fox Sports insider Jay Glazer multiple NFL teams had been informed that Burfict had failed his drug test at the NFL Combine. Burfict later stated during an interview with Scout.com that he admitted using marijuana to NFL general managers. At the conclusion of the pre-draft process, Burfict was projected to be a seventh round pick by NFL draft experts and scouts. Burfict was ranked as the ninth best inside linebacker in the draft by Scouts Inc. and was ranked the tenth best inside linebacker by DraftScout.com.

Burfict went undrafted in the 2012 NFL Draft. On April 29, 2012, the Cincinnati Bengals signed Burfict to a three-year, $1.44 million contract that featured a signing bonus of $1,000.

He made his professional regular season debut in the Cincinnati Bengals’ season-opening 44–13 loss at the Baltimore Ravens.

He led the team in tackles as a rookie and finished 15th among all players in the league. When Burfict was on field, the Bengals defense allowed 2.4 yards fewer per play, allowing 4.5 compared to 6.9 when he was off the field.

The Cincinnati Bengals finished second in the AFC North with a 10–6 record and earned a wildcard berth. On January 5, 2013, Burfict started his first career playoff game and recorded six combined tackles during the Bengals’ 19–13 loss at the Houston Texans in the AFC Wildcard Game.

He started in the Cincinnati Bengals’ season-opener at the Chicago Bears and recorded eight combined tackles, deflected a pass, and made his first career interception during a 24–21 loss. Burfict intercepted a pass by Bears’ quarterback Jay Cutler, that was originally intended for running back Michael Bush, and returned it for a 12-yard gain during the fourth quarter.
