The San Francisco 49ers are making a crucial defensive adjustment ahead of their Week 10 clash with the Los Angeles Rams. With multiple injuries weakening the defensive front, the team has turned to one of its most promising young prospects — a player whose nickname alone tells the story of his power.
For weeks, he’s been a quiet force on the practice field, earning respect through effort rather than words. Coaches have seen the spark, teammates have felt his presence, and now, his moment has arrived.
Defensive lineman Sebastian Valdez has officially been elevated from the practice squad to the active roster, setting the stage for his long-awaited NFL debut. Known among teammates as “The Hulk”
for his incredible strength and relentless motor, Valdez has built a reputation for overpowering veteran blockers during camp and practice sessions.
The timing couldn’t be more critical. With Mykel Williams sidelined by an ACL injury and Alfred Collins, Keion White, and Kalia Davis all dealing with various ailments, the 49ers needed a new source of energy in the trenches — and Valdez was the clear choice.
Coaches describe him as disciplined, humble, and fiercely competitive — the type of player who thrives when the spotlight hits. His ability to clog lanes and collapse the pocket could play a key role in limiting the Rams’ offensive rhythm on Sunday.
For Valdez, this isn’t just a roster move; it’s validation. From undrafted rookie to active contributor, “The Hulk” has powered his way into San Francisco’s defensive identity — and his NFL story is only just beginning.
