Lawrie injured his rib cage and oblique area while swinging the bat during a game against Oakland on Friday. He underwent an MRI on Tuesday night, which revealed some inflammation in the area, but a significant injury has been ruled out.
The 22-year-old Lawrie took part in Toronto's pregame stretch on Wednesday and resumed throwing, but has yet to take batting practice and is unlikely to return before the Blue Jays head back to Toronto on Friday.
"I feel a lot better than I did before," Lawrie said. "I think throwing today is kind of giving me a little light at the end of the tunnel, knowing this thing is getting better as opposed to where it was. I'm just going out there, moving around, throwing and kind of letting it fly a little bit, actually felt pretty good."
The Blue Jays will continue to monitor Lawrie's progress and have not ruled out a possible stint on the 15-day disabled list if things do not improve as expected. A big test will come on Thursday morning when Lawrie sees how he feels one day after throwing and another hurdle will occur when the native of Langley, British Columbia, picks up a bat for the first time.
For now, Lawrie continues to receive various forms of treatment in the clubhouse in an effort to speed up the healing process. There isn't much else that can be done besides rest and a timetable for his return is still very much unknown.
"I think over the next two days, we'll have a better read on that," Blue Jays manager John Farrell said of a possible DL stint.
"We have to be careful. If there's a further injury, we're looking at more of a prolonged shutdown. We'll take this step by step and make a best determination we can with his health being No. 1."
Lawrie is batting .282 with nine home runs and 40 RBIs in 100 games this season. He also has 32 extra-base hits and a .742 OPS while walking 22 times in 397 at-bats.
