Only days before he was expected back from the disabled list, Diamondbacks shortstop Nick Ahmed is hurt again.

Ahmed suffered a fractured right wrist when he was hit by a pitch during his rehab game on Sunday night and is expected to miss six to eight weeks, General Manager Mike Hazen said. That means the soonest he could come back is at some point during the postseason.

Hazen said the club will monitor the trade market for potential help but said he doesn’t expect to find much available. Players have to be in a new organization by August 31 in order to be eligible for the postseason. The Diamondbacks are expecting to get another injured shortstop, Chris Owings, back before the end of the year but he isn't eligible to come off the 60-day DL until late September.

Ahmed missed the past two months with a fractured right hand and was expected back from the disabled list sometime this week. He suffered the injury during the second game of his rehab assignment with Triple-A Reno and returned to Phoenix Monday to be examined by hand specialist Dr. Don Sheridan.

Ahmed last played on June 27, when he was struck on the right hand by a 99 mph fastball from St. Louis Cardinals reliever Trevor Rosenthal.
