DENVER -- Video replays of Tuesday's infield collision at Coors Field clearly show Ike Davis' left ankle bending in an unnatural direction. The result, the Mets now know, was an ankle sprain for Davis and a bone bruise in his ankle joint, landing him on the disabled list Thursday.
"I can't classify it as good news," assistant general manager John Ricco said.
Rather than replace Davis on the roster with a corner infielder, the Mets recalled outfielder Fernando Martinez from Triple-A Buffalo.
Davis flew back to New York City on Wednesday for an MRI exam, which revealed the two injuries in his ankle. Each injury alone was not serious, Ricco said, but the combination was enough to land Davis on the DL.
Walking around Tuesday evening with a heavy plastic boot on his ankle, Davis expressed optimism that he could play following his infield collision with third baseman David Wright. But Wednesday's MRI revealed significant damage to the ankle, and Mets manager Terry Collins indicated that Davis was in more pain than he admitted after the game.
"It's at least two weeks," Ricco said. "We hope it's not too much longer than that, but I think it's a little too early to predict."
In Davis' absence, Daniel Murphy will start regularly at first base. Justin Turner, who has never played first base in a regular-season game and who does not even own a first baseman's glove, will serve as the emergency backup.
"I'm real comfortable having Dan over there," Collins said. "He's been playing real well over there, and I'm comfortable with him at the plate."
Because Collins was committed to giving Wright and his balky back a day off on Thursday, Willie Harris was scheduled to make his 10th career start at third base. Turner was in the lineup at second, with Martinez available off the bench following an early-morning flight from Buffalo.
That alignment only underscored how much the Mets will miss Davis, the team's most productive hitter and arguably its best defender. Starting all 36 of the team's games at first base, Davis was hitting .302 with a team-high seven home runs and 25 RBIs, also leading the Mets in slugging percentage and on-base percentage.
"It's huge," Collins said of Davis' absence. "His production is going to be sorely missed."
