New York Red Bulls {{Quote_box| width=40% Ream was drafted in the second round (18th overall) of the
2010 MLS SuperDraft by
New York Red Bulls. His play during pre-season impressed many observers, including new coach Hans Backe who was pleased with his distribution and tactical awareness. On March 20, 2010, Ream started and played the full 90 minutes for Red Bulls in a 3–1 victory against
Santos FC, which was the first match played at the new
Red Bull Arena. He made his professional debut on March 27, 2010, playing the full 90 in New York's opening game of the
2010 MLS season against
Chicago Fire that ended in a 1–0 victory for New York. On September 11, 2010, he scored his first professional goal (and MLS goal) against the
Colorado Rapids in a 3–1 win for
New York Red Bulls. Ream ended his first professional season starting all 30 matches for New York and helped New York capture its second regular season
Eastern Conference title. Upon the conclusion of the 2010 season, he was named the team's Defender of the Year, and he was one of three listed candidates for
MLS Rookie of the Year. During Ream's second season in New York, he played and started in 28 of 34 matches during the regular season; he missed 6 matches largely due to international call-ups during the
2011 CONCACAF Gold Cup. In December 2011, during the
MLS off-season, Ream spent a short time training with both
West Bromwich Albion and
Bolton Wanderers with permission from the Red Bulls to maintain his fitness during the winter break. At the beginning of January 2012, Bolton made a transfer offer of £2.5m for him. Bolton had recently sold
Gary Cahill to
Chelsea, and needed to find a replacement. The bid was accepted and after personal terms were agreed he received a work permit on January 24.
Bolton Wanderers in 2015 Bolton completed the signing of Ream on January 26, 2012, on a three-and-a-half-year contract. He canceled his honeymoon so that he could sign for Bolton. He was given the number 32 shirt and made his debut for the club in Bolton's 2–0
FA Cup win at
Millwall on February 18. He made his Premier League debut the following weekend in Bolton's 3–0 defeat at
Chelsea. On March 10, 2012, he assisted
Darren Pratley's opening goal in a 2–1 win over Queens Park Rangers. He went on to appear ten games straight towards the end of the season, but was unable to help the club survive relegation in the
Premier League. For the start of the 2012–13 season, Ream was given the number 5 shirt, previously worn by
Gary Cahill. He was given his first start of the 2012–13 season in a 2–0 loss against
Burnley. However, he was sidelined from the first team, due to losing his starting place and was relegated to the substitutes bench. Despite this, Ream went on to make fifteen appearances. Ahead of the 2013–14 season, Ream was linked with a move to
Middlesbrough, a move that was denied by the club and Ream. After appearing the first three matches as an unused substitute, he started as defensive midfielder for four matches in September. In early February 2014, he was forced to wear a protective mask in Wanderers games after a collision with
Queens Park Rangers striker
Charlie Austin. Throughout the 2013–14 season, Ream played at left back and center back, where he established his partnership with
Matt Mills and redeemed himself in the first team making 42 appearances. At the end of that season, he was voted the fans' player of the year and the club's player of the year. Ahead of the 2014–15 season, on July 6, 2014, Ream signed a new three-year contract with Bolton that lasts until the summer of 2017. Over the course of the season, he made a total of 44 appearances, missing two matches, one as an unused substitute against Derby County on September 27, 2014 and one through injury. For a consecutive season, he was named as Bolton's player of the year. Ahead of the 2015–16 season, Ream was linked with a move to
Championship rivals
Queens Park Rangers, who made a bid for him. However, the bid was rejected.
Fulham in 2016 On August 20, 2015, Ream was sold to
Fulham, with whom he signed a four-year contract. The move had an undisclosed fee and an option to extend his stay by a further year. He made his Fulham debut on August 29, 2015, in a 3–1 win over
Rotherham United, playing 90 minutes. He made 29 appearances for the club in his first season, partly due to international commitment and injuries. After initially playing as a center back, he was used at left back toward the end of the season, following the departure of
James Husband. He scored his first goal for the club in a 2–1 loss against
Queens Park Rangers on October 1, 2016. Ream scored his first ever Premier League goal for Fulham on
Boxing Day 2022 against
Crystal Palace. On October 7, 2023, Ream made his 300th appearance for Fulham in a 3–1 win over Sheffield United. On December 29, 2023, Ream extended his contract with Fulham until the summer of 2025.
Charlotte FC On August 7, 2024, Ream signed for Major League Soccer club
Charlotte FC on a two-year contract with the option for a further twelve months. ==International career==
