Following his NFL career, Cabral became the inside linebackers coach at
Purdue for two seasons. In 1989, Cabral came back to Colorado and tutored the inside linebackers his first year as a graduate assistant. Cabral assumed full-time duties in the same capacity in 1990, and would remain in that capacity for two decades under
Bill McCartney,
Rick Neuheisel,
Gary Barnett,
Dan Hawkins and
Jon Embree. From 1999 through 2005, he also coached the punt return unit on special teams, and served as the director of Colorado's summer football camps from 1995 through 2005 and for a brief time as recruiting coordinator. Known as one of the top linebacker coaches in the nation, his students have included
Matt Russell, the 1996
Butkus Award winner, all-Big Eight performers
Greg Biekert,
Chad Brown and
Ted Johnson, all of whom went on to stardom in the National Football League, and all-
Big 12 linebacker
Jordon Dizon, a consensus All-American who was also the league defensive player of the year for 2007. He also recruited tailback
Rashaan Salaam, the 1994
Heisman Trophy winner, and
Chris Naeole, a 1996 All-American guard. Hawkins promoted him to assistant head coach on February 7, 2008. Hawkins cited his leadership, noting that "no one person has had more influence in the success of Colorado football than Brian Cabral." Cabral's 21 years as a full-time assistant rank as the most in Colorado athletic history, not only for football but for all sports sponsored by the University. Cabral has served twice as interim head coach for the Buffaloes. His first stint was a three-month period in 2004 before the start of the season when Head Coach
Gary Barnett was placed on paid administrative leave. In that role, he continued to coach his position players but also took care of day-to-day operational details of the program. He won his initial game as interim head coach against Iowa State after Hawkins firing, with Hawkins' son having his best game of the season. In 2013, Cabral became associate head coach and defensive coordinator at
Indiana State. ==Personal life==
