Along with Fielder, Texas second baseman Jurickson Profar is also going to sit out the remainder of the 2014 campaign, per MLB.com's T.R. Sullivan:
"Rangers first baseman Prince Fielder is expected to undergo surgery on Tuesday to repair a herniated disk in his neck and miss the rest of the season. Second baseman Jurickson Profar could also miss the rest of the season as the Rangers were hit with another double dose of bad injury news on Thursday.
"Fielder, who was examined by Dr. Drew Dossett on Thursday, is seeking a second opinion but has told the Rangers that he wants to get the surgery done now. The recovery time is 3-4 months, there is a high rate of success and the Rangers are hopeful he will be at full strength in Spring Training. But he is likely done for this year.
"'We're looking forward to getting this guy healthy and seeing what he can do,' general manager Jon Daniels said. 'But that's in 2015 and beyond. We're going to miss this guy.'
"Profar has been on the disabled list since the end of Spring Training with a torn muscle in his right shoulder. Now the Rangers have revealed that Profar has re-injured the shoulder and will have to go through the whole rehabilitation process from the beginning.
"Profar was supposed to be out 8-12 weeks, now he is looking at the same diagnosis or longer."
According to ESPNDallas.com's Richard Durrett, Fielder was supposed to take the field on Tuesday against the Seattle Mariners but eventually sat the game out due to left-arm weakness he felt during batting practice.
"Fiedler received a nerve-root injection Saturday morning and took a few days off. He passed a strength test Monday night and was penciled into Tuesday's lineup. But he was scratched after he said he felt some weakness in his left arm while trying to hit in the batting cages.
"'I wasn't surprised, just because after talking to him and seeing him, you know this was something that was bothering him,' Daniels said. 'We were hoping the injection could get him through the season. His initial response was positive. But the symptoms came back.'
"Fielder does not have a history of injuries in his career and had played 547 consecutive games -- the longest active streak in the majors at the time -- and 162 games in four of the last five seasons heading into 2014 before getting Saturday's injection.
"He was batting .247 with three homers and 16 RBIs before the injury."
Daniels explained to Durrett that Fiedler's left-arm weakness was the root cause of his lack of power. The Rangers GM also said he's proud of what his team has accomplished in spite of the rash of injuries.
"When you talk to him and when the medical staff tests his strength, he's got a real deficiency in his left arm. He's much weaker in his left arm because of this disk herniation. I have no doubt it's affected his play.
"In this case, a cervical MRI, at least for us, has not been part of our standard physical. A guy that had no history and no documentation, no treatment and no issues that anyone was aware of, had we done a physical, we wouldn't have done a cervical MRI.
"There may be other clubs that do that as standard practice. We're going to look into that. The bigger question is: 'How do we get better?'
"I'm so proud of the guys and what they've done so far. I'm not going to count this club out. They've handled adversity pretty well here."
With Fielder out, Mitch Moreland will take over at first base, per The Fort Worth Star-Telegram's Jeff Wilson.
"Mitch Moreland becomes the everyday first baseman. He was the only Rangers player to not collect a hit in their romp of the Tigers, but he's batting .305 over the past 21 games and beat out a force play at second base to extend the Rangers' four-run fourth.
"The Rangers could bring infielder Donnie Murphy off the DL or add Brad Snyder or Brian Petersen, outfielders at Triple A Round Rock.
"Daniels isn't yet considering the addition of free-agent slugger Kendrys Morales and likely would wait until after the June draft to go after him so that they wouldn't have to surrender a draft pick to sign him.
"Morales, though, probably doesn't want to come to the Rangers out of fear that he, too, would be injured."
The Rangers are third in the American League West with a 23-24 (.489) record through May 22.
