Following his playing career, Lane was an official in the NFL for 18 seasons from 1982 to 1999, serving as a side judge (1982–1991, 1998–1999) and referee (1992–1997).[2] Lane was promoted to referee after Tom Dooley retired. He retired prior to the start of the 2000 NFL season, after failing a physical. As an official, Lane was assigned to Super Bowl XXIII in 1989 and Super Bowl XXXIII in 1999 (both in Miami Gardens, Florida) and wore the uniform number 120. He was the side judge for the "Snowplow Game" in 1982 and was the referee of the "Clock Play" game in 1994.
Lane died unexpectedly in 2003 due to a heart attack.
