ARLINGTON -- A freak accident has resulted in yet another Blue Jays injury, and this time, it involved star third baseman Josh Donaldson.
Donaldson was out of the lineup in Toronto's 11-4 loss to the Rangers on Thursday afternoon because of a sore left knee. He is considered day to day, and he hopes to play in Friday's series opener vs. the Royals, but the Blue Jays won't know more until they touch down in Kansas City.
The injury took place when Donaldson was stretching earlier this week. He was using a pad on the floor, but when he went down to the ground, his knee missed the cushion and banged directly on concrete. It swelled up late Wednesday night, and it forced his absence the following day.

"I banged my knee up a little bit a couple of days ago," Donaldson said. "After last night it kind of swelled up a little bit. I told [manager John Gibbons], 'I don't think it would be a great idea to go out there and push it right now.' Hopefully, we're able to get ahead of it right now and be able to play Friday against Kansas City."
Toronto has placed 19 players on the disabled list this season, which is the club's highest total since it had 22 in 2013. The expectation is that Donaldson won't need it, but whether he's available for all three games this weekend remains to be seen.
The latest injury puts the Blue Jays at risk of having just one healthy player available off the bench for Friday's game. Left fielder Steve Pearce is also considered day to day because of a bruised right knee after he crashed into the wall during Toronto's 7-5 victory over Texas on Wednesday night.

With the team currently carrying eight relievers, there is not a lot of margin for error when it comes to the health of the roster. But more importantly, the Blue Jays need to get Donaldson back into the lineup as quickly as possible. He missed six weeks earlier this season because of a right calf injury, and Toronto can ill afford to lose him once again.
 "I feel like it's day to day, for sure, and hopefully be in there Friday," Donaldson said.
As for Pearce, he was available to pinch-hit during Thursday's game, but he would have required a pinch-runner if he reached base. All signs point to him being able to play at some point this weekend, but Friday night remains very much in doubt.
"We'll see," Gibbons said. "He'll be day to day. He might be able to come off the bench. I don't know if he'll be ready to play tomorrow. But we could always use him as a pinch-hit option."
