Emmanuel Chinedum Acho (born November 10, 1990) is an American football linebacker who is currently a free agent of the National Football League (NFL), and was drafted by the Cleveland Browns in the sixth round of the 2012 NFL Draft. He played college football at Texas.
Acho attended St. Mark's School of Texas in Dallas, Texas, where he also lettered in basketball and track and field. As a senior, he was tabbed the state's top linebacker by Dave Campbell's Texas Football and one of the 150 top recruits in the country by ESPNU. In track, he recorded personal bests of 57-4 (shot put) and 177-3 (discus).
Acho played in 48 games during his 4-year career at Texas, including 26 starts. As a senior, he was consensus first-team All-Big 12 linebacker (Coaches, AP, Houston Chronicle, San Antonio Express-News, Fort Worth Star-Telegram). He won the 2010 Arthur Ashe Award, was named to the 2011 AFCA Good Works Team, and was a three-time first-team Academic All-Big 12 selection. He was also a finalist for the 2011 Lott Trophy for college football's Defensive IMPACT Player of the Year, Lowe's Senior CLASS Award and Wuerffel Trophy. He led his team in tackles in 2011 and, over his 4-year career, recorded 278 tackles (159 solo), 41 TFL, eight sacks, seven forced fumbles, three fumble recoveries, two INTs, 13 PBU and 26 pressures.
He graduated in December, 2011 with a degree in sports management.
He was drafted by the Cleveland Browns in the sixth round of the 2012 NFL Draft. He was placed on injured reserve after a leg injury missed the entire 2012 season.  On April 11, 2013, Acho was traded to the Philadelphia Eagles for running back Dion Lewis.  He was released on September 2, 2013.  On September 10, 2013 Acho was signed to the New York Giants practice squad. 
The Philadelphia Eagles signed Acho off the Giants' practice squad on October 21, 2013.   Acho was waived by the Eagles on December 17, 2013,  but signed to the practice squad the next day.  He was released on August 30, 2014.  He was added to the Eagles practice squad the next day. Acho was promoted to the active roster on September 9, 2014. Following DeMeco Ryans season-ending injury in Week 9, Acho was thrust into a prominent role, along with Casey Matthews. In 2015, after being waived as part of the cuts to 53 due to a thumb injury,  Acho was signed back to the Philadelphia Eagles after Jordan Hicks was placed on Injured Reserve with a shoulder injury.  On November 24, 2015, the Eagles released Acho, making him a free agent. 
Emmanuel Acho is one of four hosts of "Cover Four" which airs on the Dallas Cowboys official website, and is one of four anchors at the Texas Gameday Desk on the Longhorn Network. 
Acho's older brother, Sam, won similar awards at both St. Mark's and Texas for his academics, athletics, and community service and is now a linebacker for the Chicago Bears, after four seasons with the Arizona Cardinals. 
On January 9, 2015, Eagles fan Hannah Delmonte contacted Acho via Instagram. Delmonte asked Acho to escort her to her junior prom if she received 2,000 retweets on Twitter. Acho felt 2,000 retweets was too low, so he increased it to 10,000 retweets and gave Delmonte one week to meet the goal. Less than three hours later, Delmonte posted a picture showing that she received over 10,000 retweets, and Acho accepted the invitation. 
On February 20, 2015, Emmanuel took time off from his graduate studies at the University of Texas and flew to Purcellville, VA, to personally accept Hannah's prom invitation, nicknamed 'Promposal' by the media. He surprised her with an autographed jersey that said "Prom 15" on the back. The story and the accompanying video went viral and national news outlets featured the story. On May 9, 2015, Emmanuel escorted Hannah to her junior prom in Purcellville, VA.
