After joining the 49ers via trade during the 2020 NFL Draft, seven-time Pro-Bowl left tackle Trent Williams agreed to re-work the final year of his contract.

That reworking of Williams deal allowed the left tackle to receive some of his $12.5 million base salary upfront. Giving Williams money upfront was a good-faith gesture by the 49ers to help out a player who did not receive a check last year after sitting out the season due to a grievance with Washington. 

Part of that restructured contract also means the 49ers won't be able to franchise tag Williams, sources told ESPN's Field Yates.
