San Francisco 49ers linebacker Reuben Foster suffered a concussion against the Indianapolis Colts on Thursday night and is probably out for the preseason.

49ers general manager John Lynch had said previously that Foster would probably play in the fourth preseason because of his upcoming suspension.

Foster is suspended for the first two games of the season for violating the NFL's personal conduct policy stemming from weapons and drug charges. In January he was charged in Alabama with possession of marijuana but the charges were later dropped.

Foster pleaded no contest in July to weapons charges and was given two years probation, 232 hours of community service, and $235 in fines. When the suspension was handed down Foster apologized to the team and its fans for his choices.

“I accept the League's decision and am sorry that my mistakes have hurt my team,” Foster said in a statement at the time the suspension was handed down via CBS Sports. “I have a responsibility to the 49ers, our fans and our community, and I am committed to learning from this situation and making better choices in the future. The support I have received over the last five months has been humbling, and I do not take it for granted.”

There is no question that Foster is a great talent on the field but the off the field issues are concerning. Hopefully, he has gotten the help he needs and the two-game suspension will be enough to turn around his life so he can just focus on his play on the field.
