San Francisco 49ers special teams player Demarcus Dobbs was arrested early Friday morning for marijuana possession after his involvement in a single-car accident, according to CSN Bay Area.
He did not make the team's trip to St. Louis, where the 49ers take on the Rams on Sunday.
Dobbs turned 25 on Friday.
"He was involved in a crash and we suspect he was under the influence of alcohol," California Highway Patrol Officer D.J. Sarabia said. "He was not injured and he was also arrested for possession of marijuana."
Dobbs' accident occurred on a Santa Clara, Calif., expressway at 3:45 a.m. He was not injured and was the only one in his car. He was arrested and later released. Dobbs faces misdemeanor charges.
"The 49ers are aware of the recent matter involving Demarcus Dobbs," the team said in a statement. "We are gathering the relevant facts as it pertains to this situation. We have been in contact with both Demarcus and the League office. He will not be making the trip to St. Louis, and we will reserve further comment at this time."
San Francisco added linebacker Michael Wilhoite from the practice squad to the 53-man roster.
