Webster spent 10 years playing halfback and fullback for the Giants during the 1950s and 1960s, according to reports. He scored two touchdowns in the 1956 National Football League championship game in which the Giants won against the Chicago Bears.

The New York Post reported that Webster was named to the Pro Bowl in 1958 and 1961. Webster also served as Giants head coach from 1969 and resigned in 1973. He was inducted into the team's Ring of Honor this past December. He was named the NFL Coach of the Year by UPI in 1970 after guiding the Giants to a 9-5 record, according to reports.

The Post's report also noted that Webster is fifth on the Giants career list for rushing yards (4,638) and fourth in rushing attempts (1,196).
