Mark Herzlich Jr. (born September 1, 1987) is an American sports commentator and former professional football player.

[7] Herzlich attended Conestoga High School in Tredyffrin Township, Pennsylvania, where he earned Associated Press Class First-team AAAA All-State honors as senior linebacker.

Considered a three-star prospect by Rivals.com, Herzlich was recruited by Boston College, Duke, North Carolina, Vanderbilt and Virginia.

[8] He recorded 142 tackles and made four interceptions as a junior and also lined up at fullback in 2003 and 2004, scoring three offensive touchdowns.

He led the Pioneers to back-to-back Central League titles (2004 and 2005) and became the first player in school history to win the team MVP award three times.

In November 2008, Herzlich was a projected top-15 pick by many scouts for the 2009 NFL draft but announced his return to Boston College for the 2009 season.

Herzlich missed the entire 2009 season due to Ewing's sarcoma, a rare form of bone cancer, which he overcame and earned numerous honors for his courage and outreach, including the Disney Spirit Award, Nils V. "Swede" Nelson Award, an honorary Lott Trophy, and the ACC Commissioner's Cup.

[10] On May 14, 2009, Herzlich announced that he had been diagnosed with Ewing's sarcoma, a rare form of bone cancer, stating in a press release: Obviously, I was shocked.

Now, I must channel all that energy into facing my toughest opponent yet, and that is exactly what I will do...At this point, I do not know what this means for my football future, but I am determined to rid my body of this disease so that I can put that uniform back on.

[12] He sat out the remainder of the 2009 season and returned in 2010, registering five tackles (three solo) in the season-opening 38-20 win against FCS school Weber State.

[15] On July 26, 2011, the New York Giants signed Herzlich to a three-year, $1.41 million contract as an undrafted free agent at the recommendation of owner John Mara.
