Chicago Bears' team vice president Tim McCaskey has died after a long battle with cancer.

Tim McCaskey became the Bears' vice president in 1993. He was the second oldest of team owner Virginia McCaskey's children and was the grandson of NFL and Chicago Bears founding father George Halas.

McCaskey had battled cancer for the past 17 months.

The Bears announced his death Sunday night. In a statement, the McCaskey family said he was, "as passionate, loyal, critical, analytical, committed and devoted a Bears fan as there ever was."

The Notre Dame graduate is survived by four children, eight grandchildren, 10 siblings and his mother.
