Could Kris Byrant make his Chicago Cubs' debut as early as Friday?

The Cubs placed infielder Tommy La Stella on the 15-day disabled list Tuesday due to right rib cage inflammation.

The move is retroactive to April 9.

La Stella, who was acquired from Atlanta in the offseason, was 1-for-6 in two games with the Cubs this season.

Chicago manager Joe Maddon said "it's possible" the Cubs could add an infielder for Friday's game against San Diego. Cubs President of Baseball Operations Theo Epstein didn't discount the possibility another infielder could join the team by the time the homestand ends Sunday.

Asked about Bryant potentially making his debut this weekend, Epstein said he didn't "want to speculate."

"It depends on what's happening with the roster, what's happening with his development," Epstein said. "We don't know yet."
