The San Francisco 49ers have signed defensive tackle Alfred Collins, the No. 43 overall selection in the 2025 NFL Draft, to a four-year deal worth $10.3 million, including more than $9 million fully guaranteed. The agreement, which carries a $4.1 million signing bonus and a $1.9 million 2025 salary-cap hit, completes the club’s 11-player draft class before veterans report to training camp next week. Collins’ 88 percent guarantee marks a sharp increase from the 78 percent secured by the same draft slot a year ago and is expected to serve as a benchmark for roughly 30 other unsigned second-round picks across the league, according to people familiar with the negotiations. The 23-year-old Texas product was drafted to bolster a defensive line that has undergone significant turnover since last season.
