Jimmy Garoppolo says that his two-game suspension for violating the NFL's performance enhancing substances policy was because he "messed up" the therapeutic use exemption.

The violation was related to the quarterback using a prescribed medication without having a valid therapeutic use exemption from the league, according to a source.

Garoppolo said he's never "been in this situation before," but plans to "attack OTAs, attack training camp and let those first two games pass by." He can participate in all offseason activities and training camp with the Rams, but cannot be at the facility for two weeks once the regular season starts.

"Hopefully we'll get some dubs and start off 2-0 and keep things moving," Garoppolo said. "But it's just one of those situations. It is what it is. You got to deal with it and just keep moving on and stay positive."
