Forward Robert Covington is finalizing details on a four-year, $62 million extension with the Philadelphia 76ers, according to ESPN's Adrian Wojnarowski.

Sixers general manager Bryan Colangelo has been in constant communication with Covington's representatives at CAA Sports, expecting a signed agreement as soon as the end of this week, according to league sources.

The deal is slated to include a $15 million renegotiation bump of Covington's $1.57 million salary this season, including an additional four years that's set to keep Covington under contract throughout the 2021-22 season.

The $15 million renegotiation is the largest single-season figure negotiated since the collective bargaining agreement made that possible with soon-to-be free agents like Covington, per Wojnarowski.

Covington is coming off his season-high 31 points in tandem with cornerstone Joel Embiid, as the Sixers got over the .500 mark in a statement win against the L.A. Clippers on Monday.

His play has taken a huge step up through 13 games this season, shooting 50 percent from the floor and 50 percent from deep, while being one of the best passing lane defenders at his position.

Covington is now viewed as an integral part of the core of this Sixers team along with rookie Ben Simmons and Embiid, given that his ability to space the floor efficiently and play on the wing have proven a building stone to this team's formula for years to come.

The 6-foot-9 forward is an undrafted player out of Tennessee State, who started his NBA career with the Houston Rockets before getting released and signing into the G League.

He's now transformed into one of the best three-and-D talents in the league, boasting a multi-positional defensive versatility that has made him such an important part of Brett Brown's rotation.

Covington is the Sixers longest-tenured player and is having his best season yet, averaging 16.8 points, 5.7 rebounds, 1.6 steals, and 0.8 blocks per game through 2017-18.
