why was demarcus robinson suspended

Demarcus Robinson was suspended for the first three games of the 2025 NFL season due to violating the league's substance abuse policy. This suspension stems from a November 2024 incident when Robinson was arrested on suspicion of drunk driving after being caught speeding at over 100 mph. He pleaded no contest to a misdemeanor DUI charge, resulting in three years of probation, a $390 fine, and mandatory completion of a three-month alcohol program. The NFL's suspension followed this legal matter as a standard penalty for a first- offense DUI. Robinson's suspension was officially announced by the NFL and confirmed by San Francisco 49ers head coach Kyle Shanahan. During the suspension, Robinson is prohibited from practicing or participating in the games against the Seattle Seahawks, New Orleans Saints, and Arizona Cardinals but is eligible to return in Week 4 against the Jacksonville Jaguars. The 49ers signed Robinson in the offseason with a two-year, $9.5 million contract, and his absence is a significant blow to the team's receiving corps, which has also struggled with multiple injuries.
