The Las Vegas Raiders and Darren Waller are progressing in talks on a contract extension, according to a league source.

The goal remains for a deal to get done by Sunday, when the Raiders open the season against the Los Angeles Chargers.

Waller has said he'll be playing with or without a new deal. The tight end has $6.75 million in base salary and per-game roster bonuses under his current contract for 2022.
