PHOENIX — Kwamie Lassiter, a former Arizona safety who had four interceptions in the Cardinals’ season-ending victory that clinched a playoff berth in 1998, died Sunday. He was 49.
The Cardinals announced Mr. Lassiter’s death without providing details. Arizona Sports, the website of the team’s flagship radio station, said he had a heart attack while working out.
‘‘We were all devastated to learn of Kwamie’s passing today and our hearts go out to all of his family and friends,’’ Cardinals president Michael Bidwill said in a statement. ‘‘Kwamie came to the Cardinals as an undrafted rookie free agent. He not only became a key contributor to our team for eight seasons but continued to make an impact on this community after his playing days ended.’’
The team said he created the Kwamie Lassiter Foundation which helps children fight health issues. The azfamily.com site said he leaves seven children.
Mr. Lassiter had had eight interceptions in 1998, the last four against San Diego to help the Cardinals reach the playoffs for the first time since moving to Arizona.
The former Kansas player had nine interceptions in 2001 and was named an alternate to the Pro Bowl.
After eight seasons with the Cardinals, Mr. Lassister played for San Diego in 2003 and St. Louis in 2004. He had 25 career interceptions, returning two for touchdowns.
Mr. Lassister starred at Menchville High School in Newport News, Va., and played two years at Butler County Community College in Kansas before transferring to Kansas.
