Diamondbacks reliever J.J. Putz will be placed on the 15-day disabled list with right forearm tightness, manager Kirk Gibson said after Monday night's 8-3 loss to the Milwaukee Brewers.

Gibson said Putz had been dealing with the issue in recent outings and hadn't been improving. In his most recent outing, on Saturday against the San Diego Padres, Putz gave up two runs on two hits in 2/3 of an inning.

"His last outing in San Diego, it was bothering him more than it had been," Gibson said. "It kind of trended the wrong way. We waited today to see how he was. He came in and it wasn't very good, so we're going to DL him."

Putz was with the team in Milwaukee but had left to return to Arizona before reporters were told of the injury.

Forearm injuries can sometimes mean elbow problems, and Putz has had elbow issues before. He needed surgery in 2009 to remove bone chips and a bone spur, and has had issues with his elbow ligament on multiple occasions, including last year, when he sprained his UCL.

To take his place, the Diamondbacks will recall right-hander Evan Marshall from Triple-A Reno. Marshall, a fourth-round pick in 2011 out of Kansas State, had given up just one run in 14 outings for the Aces.
