Injury updates: Drury, Monty, Kahnle, Warren

NEW YORK -- The solid play contributed by rookies Miguel Andujar and Gleyber Torres has reduced the urgency to rush Brandon Drury back to the Yankees' active roster, according to manager Aaron Boone, who said on Friday that the infielder will continue his Minor League rehab with Double-A Trenton.
Drury had his rehab transferred from Triple-A Scranton/Wilkes-Barre, as the RailRiders are hitting the road and the Thunder are opening a six-game homestand. The Yankees' Opening Day third baseman, Drury has been on the disabled list since April 7 with severe migraines.
"We've got a lot of guys playing really well on our team right now that have complicated the situation a little bit," Boone said. "I feel like Brandon is moving in a good direction. I feel like he's playing well. Thinking big picture here, we want to feel like when we do pull that trigger, he's in a good place -- not just because he's had a couple of good days, but because the problem has hopefully been squashed."
Drury's issues with migraines and blurred vision preceded his February acquisition from the D-backs, though the Yankees were not fully aware of the extent until he detailed the symptoms last month.
A New York-based specialist identified the cause as an irritated nerve between his head and neck, and Drury has been treating the issue with acupuncture and other therapies.
The 25-year-old Drury hit .385/.484/.462 in eight games with the RailRiders. Boone acknowledged that the Yankees could have hurried Drury back to the Majors if there had been a more pressing need.
"It's us wanting to put this behind us as best we can and get him to a good place," Boone said. "Hopefully, it's something that helps him in a long-term way."
The Jordan rules
Jordan Montgomery said that he was not concerned about a worst-case scenario when he exited Tuesday's 4-0 victory over the Astros after throwing seven pitches, but the left-hander still expressed relief when he was told that his left elbow strain should only keep him out for six to eight weeks.
"I feel like you kind of just know when it's something bad," Montgomery said. "I got a little nervous when I was in the MRI, just because I'm claustrophobic. I always get nervous there. I definitely felt some pounds come off my shoulders when the doctors said everything was going to be all right."

Montgomery is 2-0 with a 3.62 ERA in six starts, and he said that a possible cause for the strain could be that he has not been using his legs enough, something he has been mindful of during his pro career. Montgomery will not throw for two to three weeks, resting and working to reduce inflammation, and he said that he is eyeing a return to the big leagues around the middle of June.
"Hopefully, it's only a month and a half," Montgomery said. "It is disappointing because I was throwing the ball so well, but I'm going to try and stay as mentally sharp as I can and get back physically, and come back right where I left off."
Comeback trail
The Yankees expect to have Tommy Kahnle (right shoulder tendinitis) and Adam Warren (right back strain) return to their bullpen before the end of the month. Kahnle has been throwing for several days and is slated to throw off a mound next week. Warren has also resumed throwing, though he is thought to be behind Kahnle in terms of a full recovery.
"Those are two guys, hopefully, that we'll see back at some point this month," Boone said.
