The Red Sox are going to be without starting catcher Connor Wong for a while.

Wong suffered a small fracture on his left pinky finger during the first inning of Monday’s 6-2 loss to the Toronto Blue Jays. The injury occurred after Wong was hit on the glove by a George Springer swing, allowing the Blue Jays outfielder to reach on catcher’s interference.

Wong remained in the game for one more batter but was replaced by Carlos Narvaez when the Blue Jays came up to bat again in the top of the second. The Red Sox initially announced he’d suffered a left hand contusion, but following the game manager Alex Cora revealed the injury was more serious.

“He has a small fracture in the pinky area so he’s moving to the IL,” Cora said. “How long we don’t know, late swing got him good, so we’re going to have to make a move.”

Most fractures usually take at least six weeks to heal, but given that the injury occurred on Wong’s catching hand there may be additional recovery needed beyond what would typically be considered standard. Wong said following the game he has not been given any timetable for a return, but that he knew right away it’d taken a bad hit.

“It swelled up and was numb,” Wong said. “Obviously I was able to catch the ball afterwards so I was hopeful, but it was just kind of numb.”

Cora said the club hadn’t yet determined who would come up to replace Wong, but the logical option would be Blake Sabol, who is currently in Triple-A and is the only other catcher on the Red Sox 40-man roster. Another candidate would be Seby Zavala, who has appeared in 194 MLB games over five big league seasons.

Regardless of who fills the void on the roster, the bulk of the catching responsibility will likely fall to rookie Carlos Narvaez, who made the team out of camp as Wong’s backup and who has gotten off to a terrific start. Narvaez is 6 for 18 (.333) with a .955 OPS through his first five games this season, and following the game the 26-year-old said he feels for Wong and wants to do whatever he can to help the team in his absence.

“Nobody wants that, Connor is a very important piece for us,” Narvaez said. “Hopefully Connor will get well soon but in the meantime he’s out and I’m going to try to take accountability to help the team win every game.”
