Cubs' David Ross forced to 7-day concussion DL again

CHICAGO -- The Cubs placed backup catcher David Ross on the seven-day concussion disabled list and selected the contract of catcher Taylor Teagarden from Triple-A Iowa before Saturday night's game with the Miami Marlins.

Ross took two foul balls off the mask in Wednesday's game in New York and began experiencing symptoms Thursday. He also was hit in the head by a bat on a backswing Tuesday.

Ross has a history of baseball-related head injuries. He suffered two concussions while playing with theBoston Red Soxin 2013 and spent more than two months on the disabled list that summer. Ross met with a concussion specialist when his symptoms did not subside.

"I had a three-day headache and some nausea," Ross said Saturday. "It's nice for the seven-day DL where you can take a step back. I think the main concern is just getting another foul ball. I had that happen a couple of years ago, and it put me out about two months. I don't want to go through that again."

Ross has served as the personal catcher of Jon Lester this season. Starting catcher Miguel Montero will work with the left-hander for the first time Monday against the St. Louis Cardinals.

"I know that Miggy and Jon have been talking," Cubs manager Joe Maddon said. "I know that David's going to be very helpful talking to Miggy about the moment. I think it's going to be fine. It could be something that could benefit us down the line just in case something else were to happen. Or if you get into the playoffs, you might want to do something different."

To make room for Teagarden and left-hander Clayton Richard (who started Saturday after being acquired from the Pittsburgh Pirates for cash considerations Friday) on the 40-man roster, the Cubs moved Tommy La Stella to the 60-day disabled list and designated right-hander Gonzalez Germen for assignment.

The Cubs will have another roster move to make when outfielder Jorge Soler is ready to be activated. Soler is currently on a rehab assignment.

"We're talking about it right now," Maddon said. "It could be very, very soon."
