He played college football at Louisiana–Lafayette and was selected by the San Diego Chargers in the fourth round of the 2012 NFL draft.

[8] He entered training camp competing for the backup tight end position behind Pro-bowler Antonio Gates.

He ultimately entered the regular season as the fourth tight end on the Chargers' depth chart, behind veterans Randy McMichael and Dante Rosario.

[9] On September 16, 2012, he made his professional regular-season debut against the Tennessee Titans and caught his first career pass on a 31-yard reception from Philip Rivers.

On September 22, 2016, Green started the week 3 matchup against the Tennessee Titans and caught his first two passes of the season for 48-yards during the Charger's 17-20 loss.

[10] In his first season under new head coach Mike McCoy, Green played all 16 games, while starting 10, collecting 17 receptions for 376 yards along with 3 touchdowns.

Although he was named the backup ahead of John Phillips, Green's role with the Chargers changed under new offensive coordinator Frank Reich, requiring him to block the majority of the time as Gates was the primary pass catching tight end.

The Steelers signed him to help with a depleted tight end corps after longtime veteran Heath Miller retired during the off-season and Matt Spaeth suffered injuries which would eventually result in his failing of the team physical and release.

[16] The following day, Green made his highly anticipated regular season debut and finished the loss to the Dallas Cowboys with three catches for thirty yards.

[10] The following week, Green earned his first start with the Steelers and caught two passes for 24 receiving yards in a 27–20 victory over the Buffalo Bills.

This performance included a 28-yard third-down catch with under 4 minutes to go in the game, which moved the Steelers into Bengals' territory and allowed Pittsburgh to preserve its 4-point lead on the way to a fifth-straight victory.

However, this would ultimately be Green's final play for the Steelers during the 2016 season, as during the conclusion of his catch-and-run, upon being tackled, his head hit off the turf, leading him to be helped off the field.
