TORONTO -- Blue Jays outfielder Randal Grichuk received some good news on Sunday night, when his concussion tests came back negative following a violent collision with an on-field security guard Sunday's 6-2 victory over the Indians at Rogers Centre.
Grichuk was attempting to catch a fourth-inning foul ball down the right-field line when the incident occurred. As Grichuk slid to make the grab, he was struck on the face with a metal stool that the security guard was holding as he tried to get out of the way.
Toronto released a medical update on Sunday night to state that CT scans performed on Grichuk were negative. Grichuk has been diagnosed with multiple facial contusions and abrasions and is considered day to day, pending the results of a follow-up exam on Monday to make sure no concussion symptoms have occurred.
"They took him in to get X-rays and the concussion thing," Blue Jays manager John Gibbons said after the game. "He was conscious. I don't think he blacked out to be honest with you. I don't know that, but I saw him in the clubhouse between innings, and he was grinning and laughing a little bit, so that's a good sign."

The Blue Jays have several on-field security guards who use metal stools on the left- and right-field lines. When a ball is hit in their direction, policy dictates they are supposed to get up and move the stool to avoid a disruption in play.
The security guard was attempting to move out of the way, but he got caught between Grichuk and first baseman Justin Smoak, both of whom were converging on the fly ball. The security guard was holding the stool at a sideways angle when Grichuk slid and made contact before requiring medical attention.
Smoak doesn't believe Grichuk had any idea the security guard was still in the area when he tried to pull off the sliding grab.
"Especially here at the dome, you have to keep your eye on the ball," Smoak said. "I honestly had no clue where he was. I just peaked at Grich knowing he was coming in hot right there. We're worried about each other and the ball at the same time. No chance either of us were thinking about the security guard."
It was not immediately clear whether Grichuk would be able to travel with the Blue Jays on Monday in advance of Tuesday's series opener against the Red Sox. If Grichuk requires additional time, then the Blue Jays will continue to rotate Teoscar Hernandez, Kevin Pillar, Billy McKinney and Jonathan Davis through the outfield spots.
"They've been there since I've been here and we haven't had a problem," Smoak said in reference to the placement of the security guards. "I think it was just one of those freak accidents."
