The Cubs are expecting to be without one of their star players for roughly the next month.

Seiya Suzuki was placed on the injured list Monday afternoon with an oblique injury suffered in Sunday’s game against the Mariners.

He got imaging on the issue on Monday and the Cubs received the report back from doctors on Tuesday.

“It’s a moderate right oblique strain so we’re probably looking at around 4 weeks plus or minus,” manager Craig Counsell told Taylor McGregor before Tuesday’s 12-11 loss in Arizona. “Seeing how the next really 10 days go and how quickly we can get him symptom free.”

As Counsell said, the next week-plus could shed more light on Suzuki’s exact timeline. But he’ll be sidelined through at least the end of April and will likely be out until mid-May.

Once Suzuki is able to get back on the field and do baseball activities, he will need time to ramp up to game action. And with an extended layoff, he will probably need a rehab stint with one of the Cubs’ minor league affiliates as well.

Suzuki was off to a roaring start to the season, picking up where he left off late last year. Through 15 games, he was hitting .305 with an .893 OPS, 3 homers and 13 RBI.

In his place, the Cubs called up rookie Alexander Canario, who drew the start Tuesday night in right field.

Canario doubled home a run and scored before he was replaced by Mike Tauchman in the lineup as the Diamondbacks outlasted the Cubs 12-11 in 10 innings.
