Reliever Randall Delgado has a strained flexor tendon in his right arm, manager Torey Lovullo said, adding that his versatile right-hander will not play catch for between 10 days and two weeks.

Lovullo wouldn’t offer much more in terms of a timetable for a return, but it seems likely the Diamondbacks will be without Delgado for perhaps a month, if not longer.

Flexor tendon strains can often be precursors to or happen in conjunction with more serious injuries – Diamondbacks right-hander Shelby Miller strained his flexor at the same time he tore his ulnar collateral ligament – but Lovullo seemed to rule that out.

“I don’t know much beyond it’s a mild flexor strain,” Lovullo said. “I think the ligament is fine.”

Delgado reported discomfort in his elbow on Sunday, a day giving up four runs in two-thirds of an inning against the Braves. He underwent an MRI on Monday.

With him down, the Diamondbacks will be without a pitcher they relied on in various roles for the season’s first 3 1/2 months, often asking him to soak up multiple innings in relief appearances. He also made five starts, pitching effectively in all but one.

“For right now, we like the balance of our bullpen with the four righties and three lefties,” Lovullo said. “We have a couple of guys who can give us multiple innings. I think T.J. McFarland will take a little bit of that role if we need some length.”

Delgado was replaced on the roster by right-hander J.J. Hoover, who broke into the majors with the Reds and spent five seasons here.

“He was one of our most productive relievers for most of the first half. He had a little rut, as all players do,” Lovullo said. “I know he was struggling with some shoulder fatigue. He got that under control and I think he’s in a good place right now.”
