Jonas Gray

From Pontiac, Michigan, Gray went to high school at Detroit Country Day. He helped lead Detroit Country Day to an 11-3 record as a senior and an appearance in the state championship. He rushed for 305 yards on 29 carries and scored four touchdowns in the state semifinal to lead the Yellow Jackets to a 37-30 victory. He gained 2,614 yards on 341 rushes (7.7 avg.) and scored 32 TDs during his senior season, rushing for over 200 yards in five games. He was selected to play in the U.S. Army All-American Bowl in San Antonio, Texas. Gray also competed in track & field at Detroit County. In 2006, he placed fourth in the 200-meter dash at the MHSAA Division 3 State Finals with a time of 22.84 seconds, and as a senior, placed third in the 100-meter dash with a time of 11.13 seconds.

Gray was signed by the Miami Dolphins as an undrafted free agent. He was placed on the PUP list while he rehabbed his injured knee. He was among final cuts on August 31, 2013.

Gray was signed by the Baltimore Ravens to their practice squad on September 2, 2013.

Gray was signed by the New England Patriots to a future/reserve contract on January 10, 2014. Gray did not survive the final cuts, but was signed to the practice squad the next day. On October 16, 2014 Gray was signed to the active roster before their Thursday Night Football game against the New York Jets.

On November 16, 2014, Gray rushed for 201 yards, and a franchise-record four touchdowns on 38 carries in his fourth NFL game, leading the New England Patriots to a 42-20 victory over the host Indianapolis Colts. Gray was the first NFL running back since 1921 to score four rushing touchdowns in a game after entering the game with zero career touchdowns, and the first running back in the Super Bowl era to account for more than 25 percent of rushing touchdowns (4 of 10) in a week with at least 10 games. A correction to the official stats (removing a 2-yard loss that was negated by a 15-yard facemask penalty against the Colts) made his final stats for the game 201 yards on 37 carries. He scored 24 total points in the game, which was tied with Marshawn Lynch for the most by any player in a single game in the 2014 season.

Due to a team infraction, however, Gray was benched for the next game. He would only record 91 more total yards in the season, and was inactive for four of the Patriots remaining nine games, including the team's win in Super Bowl XLIX. Gray finished the season with 89 carries that resulted in 412 total yards and 5 touchdowns. On September 5, 2015, Gray was released by the Patriots.

The Dolphins signed Gray to their practice squad on September 9, 2015. On September 11, Gray signed to Dolphins active roster. On September 14, 2015, Gray was waived by the Dolphins, only to be re-added to the practice squad two days later and signed to the active squad on September 22, 2015. He was released again on November 10, 2015, and re-signed to the practice squad the next day.

Gray was signed off the Dolphins' practice squad to the Jacksonville Jaguars active roster on December 15, 2015. On August 17, 2016, Gray was waived/injured by the Jaguars. After going unclaimed on waivers, Gray reverted to injured reserve. On August 24, 2016, Gray was released from the Jaguars' injured reserve.
