Allen was vacationing in Mexico at the time of his death, according to the Dallas Cowboys, where he spent the first 12 years of his 14-year professional career.

A cause of death has not been revealed.

“Larry, known for his great athleticism and incredible strength, was one of the most respected, accomplished offensive linemen to ever play in the NFL,” the Cowboys said. “His versatility and dependability were also signature parts of his career. Through that, he continued to serve as inspiration for many other players defining what it meant to be a great teammate, competitor and winner.”

Allen was a Super Bowl champion and a first-ballot Hall of Famer. During his 12 years in Dallas, he was named to the Pro Bowl 10 times.

His former Cowboys teammate Emmitt Smith said, through tears, that he had been reflecting on their times together after hearing the news.

He continued, “The one thing about Larry Allen I know – he had a big heart, and he lived life to the fullest. A man of very few words, but on the football field, he was a beast, and will be sorely missed.”

Added teammate Troy Aikman: “Just received the heartbreaking news of the passing of our beloved teammate Larry Allen. He was a HOF offensive lineman that dominated opponents regardless of the position played. Off the field, he was a gentle giant that loved his family. Rest in Peace LA.”

Allen spent the final two seasons of his career in San Francisco, earning an 11th Pro Bowl selection there.

“Rest in peace Big Homie!! Only 52,” former 49ers teammate Anthony “Spice” Adams said. “Tell your loved ones, ‘I Love You’ today, tomorrow is not promised. The strongest lineman ever. Rest in Peace Larry Allen.”

“The 49ers are saddened by the sudden passing of Larry Allen who spent the last two seasons of his Hall of Fame career with the organization,” the team said. “Our thoughts and condolences are with the Allen family.”
