San Francisco 49ers Maragos was undrafted in the
2010 NFL draft. He signed with the
San Francisco 49ers on April 26, 2010. Maragos entered 2010 training camp for a 49ers club trying to build on a promising 2009 campaign. On August 22, he appeared in a nationally televised game against the
Minnesota Vikings on NBC's
Sunday Night Football. The program achieved the highest ratings for a Week Two preseason game in seven years, as it featured the heavily publicized return of
Brett Favre for a 20th and final NFL season. Despite a training camp performance that garnered favorable reviews from local beat reporters, Maragos was released by the 49ers on September 3. On September 5, Maragos was added to the 49ers'
practice squad, where he spent the first part of the 2010 season. On October 18, Maragos was added to the 49ers' active roster for a game in
Charlotte against the
Carolina Panthers, though he did not play in the contest. The following week, on October 28, Maragos and the team flew across the world to
London for a game against the
Denver Broncos. Upon arrival, Maragos was informed that he had been released from the 49ers. The rare timing of the release gained widespread attention when
ESPN reporter
Adam Schefter tweeted about the oddity. Maragos was signed to the practice squad and able to remain with the team in London, instead of being forced to fly back home immediately. He again joined the San Francisco active roster on November 30, and made his NFL playing debut at
Lambeau Field on December 5, facing the team from his home state, the
Green Bay Packers. During that game he recorded his first NFL career tackle against the eventual
Super Bowl XLV champions. After the 2010 season, the 49ers fired head coach
Mike Singletary and replaced him with Stanford head coach
Jim Harbaugh. The coaching shakeup led to an influx of new safeties, which resulted in greater competition for a roster spot. Consequently, Maragos saw his tenure with the 49ers come to end as he was released on September 3, 2011.
Seattle Seahawks Maragos was signed to the
Seattle Seahawks' practice squad on September 22, 2011. Seattle was rebuilding its roster, and head coach
Pete Carroll and general manager
John Schneider were impressed with Maragos's apparent work ethic and character. The Seahawks promoted him to the active roster on October 22. After a rough start to the 2011 season, Seattle finished the year with a 7–9 record. In 2012, the Seahawks became a legitimate
Super Bowl contender, going 11-5 and winning a road playoff game against the
Washington Redskins. During his stint with the Seahawks, Maragos was routinely awarded the team honor for "Special Teams Player of the Week." On April 11, 2013, Maragos signed a one-year contract with the Seahawks for $1.32 million. After reaching the agreement, Maragos expressed gratitude to the franchise. "It's phenomenal. Just to be in a position like this is humbling and I'm truly fortunate to be a part of such a great organization. To continue my career as a Seahawk, I couldn't be any happier." On September 6, 2013, Maragos accepted a pay cut to $855,000 to remain a Seahawk. In 2013, the Seahawks secured the top playoff seed in the NFC with a conference-best 13–3 record. After a bye week, Seattle defeated the
New Orleans Saints in the playoffs. The Seahawks then beat the San Francisco 49ers in the
NFC Championship Game to advance to
Super Bowl XLVIII. On February 2, 2014, Maragos and the Seahawks defeated the Denver Broncos 43–8 in the third-most lopsided Super Bowl in history. It was the most-watched program in the history of American television.
Philadelphia Eagles On March 12, 2014, Maragos signed a three-year, $4 million contract with the
Philadelphia Eagles. On December 6, 2015, his blocked punt was returned for a touchdown in Philadelphia's 35–28 upset win over the
New England Patriots. On November 17, 2016, Maragos signed a three-year, $6 million contract extension with $2.45 million guaranteed through the 2019 season. On October 19, 2017, Maragos was placed on injured reserve after suffering a knee injury in Week 6 against the
Carolina Panthers. It would be the final game of his career. Without Maragos, the Eagles went on to win
Super Bowl LII against the
New England Patriots 41–33, earning Maragos his second Super Bowl ring. Maragos was placed on the
physically unable to perform list to start the 2018 season while recovering from the knee injury. On February 22, 2019, Maragos was released by the Eagles. On July 16, 2019, Maragos announced his retirement from the NFL. In February 2023, Maragos was awarded $43.5 million in damages after he filed a negligence suit against doctors responsible for treating his 2017 injury. ==Personal life==
