Jon Rayborn Shields (born April 30, 1964) is a former American football offensive guard who played for the Dallas Cowboys of the National Football League. He played college football at Portland State University.
Shields attended Fort Vancouver High School.[1] He accepted a football scholarship from NCAA Division II Portland State University.
As a sophomore, he was a backup that alternated between the right and left tackle position. As a junior, he was named the starter at right tackle.[2]
As a senior, he received second-team All-Western Football Conference honors.[3]
Shields was signed as an undrafted free agent by the Los Angeles Rams after the 1987 NFL draft on April 27.[4] He was waived before the start of the season on September 7.[5]
After the NFLPA strike was declared on the third week of the 1987 season, those contests were canceled (reducing the 16 game season to 15) and the NFL decided that the games would be played with replacement players. In September, he was signed to be a part of the Dallas replacement team that was given the mock name "Rhinestone Cowboys" by the media.[6] He was a backup at right guard during the three strike games and played offensive snaps against the Philadelphia Eagles.[7] He was cut on October 20, at the end of the strike.[8]
On March 8, 1988, he signed as a free agent with the Los Angeles Rams.[9] On July 24, it was reported in the media that he left training camp for personal reasons.[10]
