At the end of the 2014 season, he became the first defensive player in Packers history to register a blocked field goal and a fumble recovery in a playoff game.

In 2017, Jones left the Packers to play with the Minnesota Vikings, but was released on September 8, 2017, after being on injured reserve with a shoulder injury.

He was also later a member of the Detroit Lions, San Francisco 49ers, Dallas Cowboys, Jacksonville Jaguars, Las Vegas Raiders and Montreal Alouettes.

[5] As a junior, at 240 pounds, he ran a personal-best time of 56.69 seconds in the 400 metres at a track meet in Long Beach.

[8] Scouts said that he had good explosion, pass rushing skills, and quickness off the ball, but also expressed concern about his techniques and moves.

[1] On October 3, against Stanford, he had 3 tackles and sacked future NFL quarterback Andrew Luck, forcing a fumble, which he also recovered.

[13] In 2010, Jones missed the entire season due to a fractured right foot he suffered in fall camp.

[1] Returning from the injury the next season, he again started every game for the team and was named to the watch list for the Ted Hendricks Award, given annually to the best defensive linemen in college football.

[17] Jones was projected to be a late first-round or early second-round pick in the NFL draft.

Additionally, he was the first UCLA player selected in the first round since Jacksonville Jaguars tight end Marcedes Lewis in 2006.

[25] Jones overcame an ankle injury suffered during the preseason and was healthy in time for the regular-season opening game; he did not miss any action during the year.

He finished the season with 10 tackles (7 solo), 3.5 sacks, and a fumble recovery, while also blocking an extra-point attempt.

He finished the regular season with 21 tackles, 1.5 sacks, an interception returned for 18 yards, 2 passes defensed, and a fumble recovery.

[30] On July 2, 2015, the NFL announced that they would suspend Jones for one game for violating the league's substance abuse policy.

[31] According to a police report acquired by the Green Bay Press-Gazette, he was cited for marijuana a day after the Packers 28–22 overtime playoff loss against the Seahawks.

On October 11, 2015, he had three quarterback hits and a blocked field goal during the team's 24–10 victory against the St. Louis Rams, earning him the Milwaukee Journal Sentinel player of the week honor.

[34] On November 19, 2015, defensive coordinator Dom Capers announced that Jones would be converted to the outside linebacker position.

[35] On March 22, 2016, head coach Mike McCarthy announced that Jones would continue playing outside linebacker and would line up as an edge rusher.

Although he was functional as a rotational player, he was unable to develop into an effective pass rusher and live up to the expectations of a first-round draft pick.

[50] Jones signed a one-year deal with the San Francisco 49ers on October 24, 2017, to bolster the team's defensive line, which was plagued by injuries.

He only played in the third game against the Seattle Seahawks, where he took part in five special teams' snaps before suffering a hamstring injury.

[56] He appeared in all four preseason games and registered 10 tackles, but was released on August 30, 2019, as part of the final roster cuts.

[62] Jones signed with the Montreal Alouettes of the Canadian Football League (CFL) on January 21, 2021, and spent over two weeks in training camp.
