Francisco Bejines made his professional boxing debut on September 16, 1977, against undefeated (2–0) Rodolfo Quintero at the Arena Coliseo in Guadalajara.
On November 25, only one month and four days after his first loss, Bejines was back in a ring as a professional, facing David Vera (6–3).
Six months later, he faced undefeated Rosendo Alonso, 6–0–1 coming in, and lost to him by ten round decision on August 11.
On September 8, Bejines returned to the winning column, notching a ten round points victory against Agustin Macias, 5–2 coming in.
On June 26, he followed that victory with a losing effort; this time against 3–4 Ramiro Garcia in a minor upset, in what was his first fight outside Guadalajara, the bout being held at Uruapan, Michoacan de Ocampo.
Bejines continued his rise on the WBC's Bantamweight rankings during 1982, meeting and defeating several ranked fighters and losing only to one, including Javier Flores, 25–12–3, beaten by seventh round knockout on January 20 at the Olympic Auditorium, Venezuelan Jovito Rengifo-who had previously challenged Lupe Pintor for the WBC world title-whom Bejines outpointed over ten rounds at the Olympic Auditorium on March 5, recent Pintor challenger Hurricane Teru, who had gone fifteen rounds with Pintor before getting knocked out in another world title fight; taken out in four rounds by Bejines June 3 at the Olympic Auditorium, and another Venezuelan, Edgar Roman, who in 1984 would challenge Richie Sandoval for his WBA world Bantamweight title and who beat Bejines by a fifth round knockout on August 12 at the Olympic Auditorium.
Meanwhile, WBC world Bantamweight champion Lupe Pintor suffered a vehicular accident and was sidelined by injury.
[3] Bejines' death was the first in professional boxing since Kim's; it was also the first involving a boxer after a fight at the Olympic Auditorium since Johnny Owen's after his unsuccessful challenge of Pintor in 1980.
