Morse was placed on the 7-day concussion DL on Tuesday, John Shea of the San Francisco Chronicle reports.

He collided with Jeff Samardzija during the dust up in Monday's game against the Nationals, and the effects of the collision are still lingering. He has a .194/.250/.306 slash line with one home run and 14 strikeouts in 40 plate appearances this season. Kelby Tomlinson was called up as a corresponding move.
