On December 10, 1993, McIver was signed to the New York Jets' practice squad. He was promoted to the active roster on January 2 and was declared inactive in the season finale against the Houston Oilers. In 1994, he was declared inactive for the first 8 games. He appeared in 4 games and was declared inactive for an additional 4 games. In 1995, he received his first NFL start at left tackle in place of an injured Matt Willig against the Buffalo Bills. He faced future hall of famer Bruce Smith and in a play that was ruled a false start, Smith hit quarterbackBoomer Esiason, knocking him out with a concussion that caused him to miss the next six weeks. He started the next 3 contests, before missing the game against the New England Patriots with a concussion. He played on special teams in the last 6 games. McIver was allocated to the WorldLeague of American Football for seasoning in 1996, where he was named the starter at left tackle for the London Monarchs. He was released from the Jets on August 7.
Miami Dolphins
On August 13, 1996, he was signed by the Miami Dolphins as a free agent. He was cut after three weeks and was later re-signed on October 7. He was named the starter at right guard against the Pittsburgh Steelers, replacing an injured Chris Gray and went on to start the last 5 games. In 1997, he earned the starting right guard position over Gray. He sprained his left knee against the New York Jets, causing him to miss two games. During the 1998 offseason, the Dolphins focused on signing free agent Kevin Donnalley and McIver eventually decided to change teams.
Dallas Cowboys (second stint)
On February 24, 1998, the Dallas Cowboys signed McIver as a free agent, because they saw a player coming into his own and with the potential for taking over Nate Newton's guard position. In training camp, he was involved in one of the most controversial episodes in Cowboys franchise history, when a fight with future hall of famer receiver Michael Irvin left him with a potentially fatal two-inch gash on his neck that required stitches. The media named the incident "Scissor gate" after the details of the event were covered up. McIver healed in time to start the first 5 games at right guard, before spraining the MCL in his right knee. He missed the next five contests and returned against the Seattle Seahawks, only to suffer an MCL tear in his left knee and being placed on the injured reserve list on November 24. The next season, he started 14 games at right guard. He was waived on February 12, 2000.
On July 24, 2000, he signed as a free agent with the Atlanta Falcons. He was released on August 19.
Scissor gate
In 1998, Michael Irvin allegedly inflicted a two-inch cut in the neck of McIver with a pair of barber's scissors, after apparently arguing over which of the two would get their hair cut first, while some team members were also in the room. McIver did not press charges, and it was rumored that Irvin paid a six-figure settlement with him to drop the matter. The incident came to be known as "Scissor gate".
Personal life
In 1997, he won the celebrity division in the Cal Dixon Celebrity Offshore Fishing Classic.
