The suspension, without pay, was caused by a violation of the league's policy on performance enhancing substances.
Love will be eligible to return to the team's active roster on Sept. 29, after the Vikings' meeting with Pittsburgh. He will be allowed to take part in preseason practices and games.
Love was drafted in the sixth round of the 2011 draft but has yet to play in a regular-season game. He missed all of last season due to an injured pectoral muscle.
