The Colorado Rockies will place outfielder David Dahl on the 7-day disabled list with a back related injury, according to manager Bud Black.

Dahl was unexpectedly removed from Monday’s game while on a rehab assignment with the Triple-A Albuquerque Isotopes and was not in the lineup the following day. When manager Glenallen Hill was asked about Dahl, he responded with “No comment.”

Ahead of Wednesday’s matchup with the New York Mets, Black gave a brief, vague update on the 23-year-old.

“I did hear today that he was going to go on the disabled list,” Black said. “7-day disabled list … I think it’s back-related.”

Dahl has yet to play this season due to a complicated return from a stress reaction in his ribs that he suffered during Spring Training.

Nick Groke of the Denver Post reports that Dahl has been out of the lineup with back spasms and that the Rockies are being cautious with him.

Dahl was impressive in his stint with the Rockies last season. In 63 games, Dahl hit .315 with seven home runs and 24 RBIs for Colorado.
