SAN DIEGO -- The Colorado Rockies have placed catcher Tony Wolters on the seven-day concussion disabled list.
He was hurt in the seventh inning Tuesday night when he got hit in the helmet by Hector Sanchez's backswing. He departed a few pitches later.
The Rockies also reinstated left-hander Mike Dunn from the 10-day disabled list on Wednesday, selected the contract of catcher Ryan Hanigan from Triple-A Albuquerque and optioned right-hander Carlos Estevez to Triple-A.
Dunn was placed on the DL on April 26 with back spasms.
