The Toronto Blue Jays placed veteran right-hander Max Scherzer on the 15-day injured list with left ankle inflammation and right forearm tendinitis on Monday.

The 41-year-old has been one strikeout shy of a milestone 3,500 for the past nine days but couldn't hit that mark in losses to the Arizona Diamondbacks on April 18 and the Cleveland Guardians on Friday.

His outing against the Guardians garnered no strikeouts and drove his ERA to 9.64 after giving up seven earned runs on 82 pitches in 2 1/3 innings, though Scherzer said after the game, "I would not characterize this start as the fault of my forearm."

Scherzer has reportedly been dealing with the forearm tendinitis since early April.

"The doctor said, ‘Hey, take five or seven days, let this all heal, and then ramp back up and you'll see," Scherzer said Monday. "'Your body will tell you how fast you can ramp up.'"

It's unclear who will fill in for Scherzer's next scheduled start on Wednesday. Left-hander Eric Lauer had been expected to move to the bullpen when Trey Yesavage is activated for his season debut Tuesday against the visiting Boston Red Sox after starting the season on the IL with a right shoulder impingement. Lauer could be moved back to the starting rotation in light of Scherzer's injuries.

Reliever Chase Lee was called up to fill the 26-man roster on Monday but another move will need to be made for Yesavage's return.

Scherzer's move to the IL is one in a long list for the Blue Jays this season, a group of more than a dozen players that also includes designated hitter George Springer (fractured left big toe); outfielders Addison Barger (sprained left ankle), Anthony Santander (torn labrum in left shoulder) and Nathan Lukes (hamstring strain); catcher Alejandro Kirk (fractured left thumb); starting pitchers Bowden Francis (elbow surgery), Jose Berrios (stress fracture in right elbow), Cody Ponce (torn ACL in right knee) and Shane Bieber (right elbow inflammation); and right-handed reliever Yimi Garcia (elbow).

The Blue Jays sit in fourth place in the AL East with a 12-15 record. They open a three-game home series Monday against the Red Sox.
