Gurode attended the University of Colorado, where he played for the Colorado Buffaloes football team from 1998 to 2001. He was a four-year starter for the Buffaloes, playing both center and guard on the offensive line. He started his first two and a half seasons at center, before moving to guard in the middle of his junior year. As a junior in 2000, he started the first six games of the year at center and the final five games at guard. He received the John Mack Award, as selected by the coaches for being Colorado's most outstanding offensive player and was also selected honorable mention All-Big 12 Conference honors while helping the Buffaloes to a 7–5 record and a win over the Boston College Eagles in the Insight.com Bowl. As a senior, he started every game at right guard. Gurode was a first-team All-Big 12 selection in 2000 and 2001, and was recognized as a consensus first-team All-American as a senior in 2001. During his career he allowed just 7.5 sacks in 2,653 plays as a starter for the Buffaloes. He earned a degree in ethnic studies from the University of Colorado, where he was a member of the school's "Academic Starters" team.
Gurode initially projected as a guard and was ranked the best available in the 2002 NFL Draft, along with Kendall Simmons. He was regarded as an early second round pick, and was eventually selected 37th overall by the Dallas Cowboys.
Gurode was drafted by the Dallas Cowboys in the second round of the 2002 NFL Draft as a center. He started fast by becoming the first rookie in club history to start at center on opening day. It is believed 2002 was the first time a NFL franchise had five African-American starters on their offensive line, when the Cowboys lined up Gurode at center, tackles Flozell Adams and Solomon Page, guards Larry Allen and Kelvin Garmon. Gurode also became part of history as the starting center on the Cowboys offensive line that helped Emmitt Smith eclipse Walter Payton as the NFL's all-time leading rusher, playing against the Seattle Seahawks on October 27. While he started the first six games of the 2002 season at center, Gurode was moved to help compensate for the number of injuries along the offensive line, compiling another eight starts at right guard. In 2003, Bill Parcells was hired as the Cowboys head coach and decided that Gurode's best position was at guard, starting 15 games at that position in 2003 and 13 games in 2004 with mixed results, before getting benched for the final two games. At the start of the 2005 season, Parcells accepted he made a misjudgment by moving Gurode to guard and switched him back to center, with the Cowboys also signing Marco Rivera to take his place at guard. That season, he was a versatile backup, playing behind Al Johnson at center and Rivera at right guard. In 2006, he rededicated himself to football and won the starting center job again, over Al Johnson. On October 1, 2006, in the third quarter of a game against the Tennessee Titans, Titans defensive tackleAlbert Haynesworth stomped on Gurode's head. Haynesworth's cleats caused a laceration requiring thirty stitches. Haynesworth was ejected, and subsequently suspended by the NFL for five games without pay. Following the 2006 season, Gurode was named to his first Pro Bowl as an injury replacement. On February 20, 2007, the Cowboys re-signed Gurode to a six-year contract worth US$30 million including a $10 million signing bonus. Gurode developed into one of the league's most respected centers since returning to being a full-time starter in 2006, and has been selected to the All-Pro Team, as well as to five straight Pro Bowls He had offseason left knee surgery and missed the 2011 seasontraining camp and three out of four preseason games. With the emergence of second-year player Phil Costa, he was released after the preseason following failed negotiations regarding a restructured contract.
On November 27, 2012, the Chicago Bears signed Gurode after losing guards Lance Louis and Chris Spencer to injuries sustained in a game against the Minnesota Vikings on November 25. He was waived by the Bears on December 11, 2012.
