High school career
Thornton was born in Panama City, Florida and attended Bay High School there, where he made 49 tackles including 46 solo stops, two sacks, three forced fumbles, and one fumble recovery as a senior. He also played fullback, recording 678 yards rushing with 10 touchdowns. He did not qualify academically for the NCAA standards, leading him to spend one year at Hargrave Military Academy in Chatham, Virginia.

He was considered a four-star recruit by Rivals.com. He was ranked 16th among prep school prospects, and the 20th best prospect at defensive tackle in 2008 by ESPN. He was named to the Orlando Sentinel Top 100 and played in the North-South Football All-Star Classic.

He worked construction while he was in high school.

College career
Thornton was well recruited coming out of school and had received interest in a number of schools including Arkansas, Clemson, Florida State, and South Florida. After originally committing to South Florida, he had not been approved by USF's academic committee, despite meeting the NCAA standard. He enrolled instead at Southern Miss, and was given a redshirt designation in 2009.

Thornton started his career with the Golden Eagles by playing in all 13 games in 2010 and recording 17 tackles, five tackles for loss, and 2.5 sacks. He had his best game of the season against Prairie View A&M where he recorded three tackles.  At the end of the season, he was selected to the Conference USA All-Freshman team as voted on by the league's head football coaches.

In 2011, he appeared in 14 games, starting seven at defensive tackle, and tallied 24 tackles, nine tackles for loss and 1.5 sacks with one pass batted, one forced fumble and one fumble recovery. During the 2011 Hawaii Bowl, Thornton had two tackles and one half-sack.

Thornton was Southern Miss's primary defensive tackle in 2012, playing in 12 games and starting 11 of them. During the game against Western Kentucky, He intercepted a pass and returned it 12 yards.  He ended his junior campaign with 36 tackles, 23 of which were solo, 9.5 tackles for loss which was the second-best on the team. He also had one sack and a forced fumble.

In his final year with the Golden Eagles, Thornton started 11 games and was voted a team captain by the other players. He had his best game of the season against Florida International University, where he had a season-high seven tackles, 2.5 of those for a loss, and added on half a sack.  In eight games he had at least three tackles, and five stops in four contests. Thornton missed the final contest of his collegiate career due to a deep bone bruise that caused some internal bleeding he sustained the week before against Middle Tennessee. He finished up the year with 39 tackles (16 solo), 6.5 tackles for loss and half a sack. For his efforts, he was named to the All-Conference USA second-team as a defensive lineman by the league's coaches. He was a finalist for the Conerly Trophy, which is given annually to the state's top collegiate player. Although he was beaten for the award by Gabe Jackson, an offensive guard from Mississippi State.

He finished his collegiate career with 50 games played, 28 starts, 116 tackles (58 solo), 30 tackles for a loss, 5.5 sacks, two forced fumbles (one recovered), an interception, and three defended passes.

Professional career
Thornton received an invitation and played in the NFLPA Collegiate Bowl, becoming only the second Southern Mississippi player to attend. During the game, he was noted up as "frequently taking up multiple blockers" and that he showed fast hands and an ability to pressure the quarterback. He recorded one sack in the game.

To prepare for the NFL Combine, Thornton reportedly worked out at the EXOS facility in Gulf Breeze, Florida at the recommendation of former teammate and current Detroit Lions linebacker Jamie Collins. He entered the facility at six-foot-three inches tall and weighing 300 pounds. One of the trainers there said that he was so big he had to cut a slit in his shirt to get it over his head.

During an interview at the facility, Thornton said that scouts had told him he needed to work on keeping his pads low, but he was more focused on running a fast forty yard dash and his bench press.

Thornton was projected to be drafted in the late fifth or early sixth round by NFL Scouts. Scouts said that he had great strength and quick hands, and was very versatile on the defensive line with good bursts of speed. He was said to have short arms and small hands and could do a better job working off blocks and protecting his legs. Stamina was a concern, as was his lack of pass rush moves. He missed a lot of tackles and did not have that many sacks. Scouts were concerned that he did not face top talent at the collegiate level. One of scout's biggest concerns was how often he took plays off from the game. He offered a rebuttal about taking plays off saying that he still ran towards the ball and that he never gave up on a play, and that he always encouraged his teammates to do the same. Overall, he was projected to be a project player and a good fit in schemes used by the New York Jets, Baltimore Ravens, or Pittsburgh Steelers

Thornton was drafted by the Green Bay Packers in the third round (85th overall) of the 2014 NFL Draft.  He was the fifth defensive lineman drafted by Packers' General Manager Ted Thompson in three years. Mike Mayock commented that the Packers had drafted a player who "flies all over the field. He can play inside, but he moves along the line of scrimmage. There's an energy, there's a motor." Thornton admitted that he was surprised to hear his name as one of the Packers' two picks in the third round. Thompson has said that Khyri kept catching the Packers' eye even though he didn't play on a team that won a lot of games.
It was predicted by the media that the Packers would move him from defensive tackle to defensive end or they would attempt to convert him to nose tackle. He was not projected to star in the scheme, but was expected to be part of the defensive rotation

Green Bay Packers
Thornton signed his rookie contract on May 19, 2014.  His former defensive coordinator at Southern Miss, Derrick LeBlanc commented that Green Bay was going to get a guy who would work hard every day and that he has the talents for a long career in the NFL.

During training camp, Thornton noted that he had played in five schemes in five years while in college and believed that that experience would allow him to fit in anywhere on the defensive line. He commented saying that he would play whatever position the coaching staff wanted him to play commenting "Wherever I can get in, to fit, to make us win, I'll play it. I enjoy playing. I'm gonna give my effort, 100 percent."

In his first preseason, he recorded six tackles in four preseason games and was considered "on the bubble" for a roster spot. Packers head coach Mike McCarthy said that Thornton was "Raw" and that "This is a whole different system for him. Everything's new. But, boy, he's got a lot of fast twitch in his body for a big man." He played more snaps then anyone on the defensive line with eighty during the preseason.
