NFL suspends Bolden for four games

New England Patriots rookie running back Brandon Bolden has been suspended without pay for four games Friday for violating the league's policy on performance-enhancing substances.

The undrafted free agent out of Ole Miss has rushed for 234 yards and two touchdowns in six games this season, but missed the last two games with a knee injury.

Bolden, who ran for a career-high 137 yards on 16 carries in a win over Buffalo on Sept. 30, had not practiced so far this week. He is eligible to return to the active roster Dec. 3, following New England's game against Miami.
