MILWAUKEE _ 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.
In a worst-case scenario, "it's sub-optimal," manager Joe Maddon said.
The Cubs are already without two-time All-Star shortstop Javier Baez, who could be ruled out for the remainder of the regular season. Baez was scheduled to be examined by a hand specialist Monday to determine how long he will be sidelined after an MRI revealed a hairline fracture of his left thumb.
Maddon noticed that a few drips of blood fell from Russell's nose and that his eyes were watery. But after being examined by several medical staffers and Maddon for about five minutes, Russell walked to first base.
Russell stole second base on the next pitch on his own and scored the tying run, but Maddon and the medical staff thought it was wise to take a closer look at him.
That prompted David Bote to take over at shortstop for the remainder of the game, and he likely will start at shortstop Monday night against the Padres if Russell isn't cleared to play.
Ben Zobrist also can play short if needed.
