The NFL suspended San Francisco 49ers linebacker Clark Haggans for three games for violating the NFL's substance abuse policy, the team announced in a statement.
Haggans was suspended as a result of his guilty plea on a charge of extreme DUI. Extreme DUI is for driving with a blood alcohol level of higher than .15.
“We were certainly aware that this decision was a possibility as we evaluated Clark prior to adding him to our roster. Therefore, we are prepared to move forward accordingly," 49ers general manager Trent Baalke said.
This is Haggans second time being convicted of DUI and he is eligible to return to the active roster on Oct. 8.
Haggans, 35, has dressed for the 49ers first two games but did not see the field.
Haggans, who played with Arizona Cardinals the past four seasons, served jail time for the DUI charge in June.
