Secondary numerals (called "TV numbers") first appeared on the jersey sleeves in 1961. Over the years, there have been minor revisions to the sleeve stripes, the first occurring in 1968 (brown jerseys worn in early season) and 1969 (white and brown jerseys) when stripes began to be silk screened onto the sleeves and separated from each other to prevent color bleeding. However, the basic five-stripe sequence has remained intact (with the exception of the 1984 season). A recent revision was the addition of the initials "AL" to honor team owner Al Lerner who died in 2002; this was removed in 2013 upon Jimmy Haslam assuming ownership of the team.
