Miami Dolphins

Carroll was selected by the Miami Dolphins in the fifth round (145th overall) of the 2010 NFL Draft.^[8] The pick was received in a trade with the San Francisco 49ers for wide receiver Ted Ginn Jr.^[9] He was considered one of the team's most promising rookies, and saw action on special teams during the preseason.^[10] In Week 4, he handled kickoff return duties against the New England Patriots.^[11] Carroll was part of an improved Miami special teams unit two weeks later against the Green Bay Packers, a game in which he averaged 26.0 yards per kickoff return.^[12]

On December 13, 2010, New York Jets strength and conditioning coach Sal Alosi extended his knee to trip Carroll as he was running out of bounds to avoid being blocked during a punt (it is illegal to block or tackle players out of bounds, non-players like Alosi are not permitted to be on the field during live play.)^[13] Ex-Dolphin Zach Thomas later claimed that Alosi had ordered a wall formed on the edge of the coaching box in order to prevent the practice of players running out of bounds to avoid being blocked. Alosi was eventually suspended for the rest of the 2010 season.^[14] In the same game, Carroll recorded his first career interception when he picked off Jets' quarterback Mark Sanchez.^[15]

In 2012, after cornerback Richard Marshall was placed on IR, Carroll was elevated to the starting role for the majority of season.

Philadelphia Eagles

On March 13, 2014, he signed a two-year, $5 million contract with the Philadelphia Eagles.^[16] He started in the last game of the season against the New York Giants.

In 2015, he was named the starter at cornerback opposite Byron Maxwell. On September 20, during the home opener loss against the Dallas Cowboys, Carroll tackled a fan who ran on the field.^[17] On October 19, in the Monday Night Football game vs. the New York Giants Carroll intercepted Giant's quarterback Eli Manning and returned the interception for a touchdown giving his team a 14–7 lead (the Eagles won the game 27–7).^[18] On November 27, he was placed on injured reserve list with a broken right fibula he suffered against the Detroit Lions. He finished with 11 starts.

On March 15, 2016, Carroll re-signed a one-year, $2.36 million contract.^[19] He started 16 games, registering 4 tackles and one interception.

Dallas Cowboys

On March 10, 2017, Carroll signed a three-year, $10 million contract with the Dallas Cowboys, to help replace cornerbacks Brandon Carr and Morris Claiborne who left in free agency.^[20] On May 29, he was arrested on suspicion of driving while intoxicated.^[21]

Although he struggled in preseason, he was named the starter at right cornerback for the season opener. He suffered a concussion in the second game against the Denver Broncos and was declared inactive for the next three contests. On October 11, Carroll was released after playing less than six full quarters.^[22]
