Toronto's designated hitter originally set a goal for Tuesday to resume his offensive work, but that timeframe came and went without any progress.
"We didn't even put a bat in his hand today," Blue Jays manager John Farrell said. "There's still some swelling and [while] the strength in the right hand is improving, it's still not to the point his left is, and we don't want to re-aggravate things and set him back any more. He's the classic case of being day-to-day right now."
Encarnacion suffered the injury when he was hit on the right hand by a fastball from Red Sox starter Daniel Bard. The club initially feared the worst but a series of X-rays and CT scans did not reveal a fracture and he was instead diagnosed with a deep bruise.
The swelling has gone down since the incident on Sunday, but is still present on the backside of the hand.
Encarnacion's hand injury drew some comparisons to the one suffered by third baseman Brett Lawrie last year in Triple-A Las Vegas. Lawrie was initially diagnosed with a bruise, but after the swelling went down it was later revealed a fracture had occurred.
Farrell doesn't believe that will be the case with his starting designated hitter, who is batting .279 with 17 home runs and 43 RBIs in 54 games this season.
""At this point no," Farrell said. "Brett's swelling was almost two or three times the thickness of his normal hand, so we did take every test possible. If it gets to the point where he plateaus and is not really feeling better, we would re-administer those tests, but at this point, everything points to him getting back."
