The Philadelphia Eagles will sign a four-year, $64-million contract extension with their left tackle Jordan Mailata, according to ESPN's Adam Schefter who learn it from Mailata's agents on Saturday.

The deal contains $40.85 million of guaranteed money and can be worth up to $80 million at most, confirmed Mailata's agents Jeff Nalley and Graylan Crain to ESPN.

"Excited to be here for another four years, representing this team and city. I can't wait to keep representing my family and everything that I have in me. Give it to you guys to get this championship here. Remember, Go Birds, baby!" Mailata said in a video posted by the Eagles on Twitter.

As a former Australian rugby player, Mailata was brought to IMG Academy in January 2018 by the NFL's International Player Pathway program. Despite his remarkable athleticism, he had no idea how American football worked at the beginning. That partly explained why the Eagles selected him with the 233rd pick in the 2018 NFL Draft.

Instead of playing in the league, Mailata spent his first two seasons training with offensive line coach Jeff Stoutland and achieved excellent improvements with his skills. Last season, he started 10 games for the Eagles and became great help for the team's offensive front, especially when they were struggling with injuries.

Though Mailata is still a work in progress, he could play a key role in the rebuilding process of the Eagles.

The Eagles are challenging the Atlanta Falcons in their season opener at Mercedes-Benz Stadium on Sunday.
