Lundy took his family's advice and began a successful amateur boxing career in which he finished 65–5 overall and won the 2003 Pennsylvania Golden Gloves.

[1] Lundy began his professional career in 2006 under the guidance of promoter Jimmy Burchfield Sr. and Classic Entertainment and Sports, defeating Steve Thomas by first-round knockout at the Cape Cod Melody Tent in Hyannis, Massachusetts.

This time, Lundy earned the win, narrowly beating Almarez by unanimous decision, 38–37, 38–37, 38–36 at the Twin River Casino in Lincoln, Rhode Island.

Lundy began 2010 with another tough challenge, facing former Cuban amateur standout Richard Abril at The Roxy in Boston, Massachusetts, on January 22.

[6] Three months after winning the title, Lundy made his first defense against John Molina Jr. in the main event of ESPN's Friday Night Fights at Twin River Casino in Lincoln, Rhode Island, on July 9, 2010.

[8] Lundy earned another shot at a title on April 1, 2011 when he faced former Venezuelan Olympian Patrick Lopez for the vacant NABF lightweight championship on Friday Night Fights at Foxwoods Resort Casino.

Referee Gerald Scott threatened to stop the fight due to the damage over Diaz's eye, but ultimately allowed the former world champion to continue.

The match was scheduled as the 10-round main event of ESPN's Friday Night Fights on March 30, 2012, at the Foxwoods Resort Casino's MGM Grand Theater.

On July 27, 2012, Lundy defended his title against Mexican challenger Ray Beltran in the main event of ESPN's Friday Night Fights at Resorts Casino Hotel in Atlantic City, New Jersey.

Lundy gave Postol his toughest test to date, particularly in the late rounds of their scheduled 12-round bout, but lost a 116-112, 116-112, 116-113 unanimous decision.

[10] Shortly thereafter, Lundy returned to ESPN's Friday Night Fights in Salem, New Hampshire, to face 33-year-old Nigerian veteran Ajose Olusegun in the 10-round main event at Rockingham Park on July 19, 2013.

Despite taking the fight on short notice, Lundy pieced together arguably his most impressive performance to date, dominating Olusegun to earn a 100-90, 98-92, 98-92 unanimous decision win.

Lundy put his winning streak on the line in his HBO debut against NABF super lightweight champion Thomas Dulorme on December 6, 2014, at the Barclays Center in Brooklyn, New York.

[13] A month later, Lundy agreed to fight Boxcino lightweight tournament champion Petr Petrov on just eight days' notice in the main event of an ESPN telecast at the Turning Stone Resort & Casino in Verona, New York.

[14] Lundy fought again on national television on July 11, 2015, this time challenging Mauricio Herrera in the main event on HBO Latino for the vacant NABF 140-pound title.

Lundy lost on the scorecards via technical decision when the fight was stopped toward the end of the fifth round due to a pair of cuts over each of Herrera's eyes caused by accidental head-butts.

[16] On October 17, 2015, Lundy made his long-awaited return to the lightweight division at Mohegan Sun in Connecticut, defeating Carlos Winston Velasquez by fifth-round knockout to capture the vacant WBC Continental Americas Titles.

Panned as a second-rate fight for the undefeated Crawford, the bout picked up considerable steam in the weeks leading up to the telecast as Lundy boldly predicted a knockout win.
