Houston Astros slugger Yordan Alvarez will be sidelined at least four weeks with the oblique strain that landed him on the injured list Friday.

Astros general manager Dana Brown gave the update on the timeline for Alvarez's return Wednesday during an interview on SportsTalk 790 AM.

"It's going to take at least two weeks for us to get a feel for how it's healing," Brown said.

"You take those two weeks and then another week to figure out when he starts to have some activity, and OK, how's his body responding? That's three weeks right there. You're looking at, once he's starting to swing a bat, maybe it's four weeks or so."

Alvarez aggravated the oblique on his final swing in the batting cage before exiting after his lone at-bat in Houston's 3-2 loss Thursday to the Toronto Blue Jays.

Alvarez, 25, is hitting .272 with 17 homers and 55 RBIs in 57 games this season.

The American League Rookie of the Year in 2019, Alvarez is batting .293 with 115 homers and 338 RBIs in 425 career games with the Astros.
