Mitch Moreland is not going to have reconstructive surgery on his ankle, and instead will have a more minor procedure to remove a bone, per Evan Grant. If this procedure works, then Moreland could end up missing just 3-4 weeks, rather than the 3 months that was originally announced.
The procedure is the same one that Geovany Soto underwent this spring. Soto then later tore the meniscus in his knee, which required surgery and has kept him out most of the year, but that is a separate issue from the ankle injury.
This is potentially good news for the Rangers, who currently have a big gaping hole at first base and no one to fill it. If Moreland can come back and perform like he has the past several seasons, that would be an upgrade over Donnie Murphy, Brad Snyder, who whoever else the Rangers would be looking to to fill for Moreland in his absence.
