The Cubs’ shortstop depth could be stretched to extreme levels, pending the results of tests on Addison Russell.

Russell suffered a nasal bruise and was under examination for a potential concussion after getting beaned by a pitch from the Brewers’ Adrian Houser in the third inning of an 8-5 loss.

Russell accompanied the team on its flight to San Diego but was unavailable for comment, per rules regarding examinations for concussions. Russell, wearing a Forrest Gump jersey as part of the Cubs’ football-themed trip, talked to a few teammates after the game but will continue to undergo tests.
