Former NFL star Marion Barber III died at the age of 38, the Dallas Cowboys confirmed in a statement on Wednesday (June 1).
"We are heartbroken by the tragic death of Marion Barber III," the team said. "Marion was an old school, hard-nosed football player who ran with the will to win every down. He had a passion for the game and love for his coaches and teammates. Our hearts go out to Marion's family and friends during this difficult time."
Barber's cause of death is currently unknown. Police in Frisco, Texas said in a statement that they were conducting a welfare check on an apartment "believed to be leased" by Barber and responded to an unattended death there, but did not name the individual in their report.
"The NFL mourns the tragic loss of Marion Barber III and we extend our deepest condolences to his family and loved ones," the league wrote in a statement.
Barber was drafted to the Dallas Cowboys in 2005 and is fourth in franchise history with 47 rushing touchdowns. He played for the Cowboys for six years before playing a final season in Chicago for the Bears in 2011.
Members of the sports world took to Twitter to remember Barber for his tenacity on the field.
