BOSTON -- A day after being hit in the helmet by an 89 mph changeup from the Seattle Mariners' Felix Hernandez, Red Sox shortstop Xander Bogaerts is out of the lineup for Saturday's game and still undergoing concussion tests. Bogaerts was removed from Friday's game an inning after being hit.
"Anytime you get hit in the head like he did last night -- removed from the game -- he's got to go through a protocol, which he's going through today, to see if there's any concussion symptoms," Farrell said. "That's what's taking place this morning."
Initially, Bogaerts stayed in the game after being checked by trainers, a decision that Farrell explained.
"All the field tests -- the eye test, the walking of a straight line, having him stand there with his eyes closed -- all those were negative results," Farrell said. "It was determined at that point that he could continue based on his response to questions and all that our trainers put him through in the moment. Not uncommon as time goes on that you start to feel the onset of symptoms. That was the case last night, and that's when he was removed."
Farrell also offered an update on starting pitcher Joe Kelly, who was removed for precautionary reasons Friday night after feeling a tweak in his shoulder while throwing a curveball. Kelly had thrown five one-hit innings before being replaced in the top of the sixth.
"Joe came in and felt no ill effects from last night after a battery of tests that he went through after the game last night that didn't reproduce any of the symptoms," Farrell said. "It was followed up with him feeling well this morning. He's on target to start in five days."
• As of his pregame press conference, Farrell had yet to make a determination as to whether or not closer Koji Uehara would be available Saturday if needed. It would seem unlikely, as Uehara allowed five runs in the ninth inning Friday night, throwing a season-high 38 pitches and blowing his third save opportunity this year.
Farrell said he had the chance to talk to Uehara about his outing.
"He's disappointed. I talked to him briefly after the game last night. He's fully accountable as we've known from his time here. Disappointed, but they strung together a number of at-bats to combine for the five runs. Everyone is going through their throwing program right now, so I'll have a better idea after they're done with who's available and who's not today."
• After being held out of the starting lineup since Tuesday battling back spasms, first baseman Mike Napoli is in Saturday's lineup, batting fifth.
