Vladimir Guerrero Jr. is on the injured list. The Blue Jays placed their first baseman on the 7-day concussion IL after he exited a game following a collision with Yankees shortstop George Lombard Jr. at third base, per Keegan Matheson on MLB.com.

The move is an official roster transaction, meaning Guerrero Jr. is unavailable for at least one week. What remains unconfirmed is any timetable beyond that minimum — concussion protocols don't run on a fixed clock, and the Blue Jays have not announced a projected return date.

The timing

The IL placement lands on a day that was already carrying some weight in Toronto. Ricky Tiedemann made his MLB debut, pitching one inning with a fastball sitting 96-97 mph, and manager John Schneider described the team's current vibe as the best it has been all year. Guerrero Jr.'s absence is a notable counterweight to that momentum.

What we don't know yet

The Blue Jays have not detailed how Guerrero Jr. is progressing through concussion protocol, nor have they indicated who, if anyone, will absorb his lineup spot in the near term. The day's game against the Yankees featured S. Woods Richardson starting for Toronto, with the lineup already adjusted for Guerrero Jr.'s absence.
