He told reporters he doesn't know much time he will miss.
Murphy, 29, is expected to earn around $9 million through salary arbitration in 2015, after which he can become a free agent.
He has said he is open to signing a contract extension to stay with the Mets.
According to MLB Trade Rumors, based on his position, age and stats, Murphy warrants a a four- or five-year contract extension worth around $12 million per season (MLBTR, June 26).
He had been on pace to finish this season batting around .300 with 10 HR, 40 doubles and 80 RBI, making him one of the top two or three most productive second basemen in the National League.
The Mets have reportedly listened to trade offers for Murphy at various points during the last year, but the asking price was ‘substantial,’ according to multiple reports (ESPN, July 25) Rubin, Dec. 11).
In Murphy's absence, the Mets will start 20-year-old 2B prospect Dilson Hererra, who has drawn rave reviews from MLB.com's Jonathan Mayo, ESPN's Keith Law, scouts and his manager in Single-A >> Read more.
Matthew Cerrone: So, the big question is: Let's say Herrera plays lights out in his debut, what does this mean for Murphy's future with the Mets? I'll say this, it's a good problem to have, right? It's better than what this franchise has going on at shortstop. It's also worth noting Hererra used to play shortstop...
To me, in a perfect world, Murphy stays at second and Herrera goes to shortstop. But, he hasn't played there very much and he appears to be more natural at second base. So, if he's going to be a second baseman, then what?
The way I see it, the question for Sandy Alderson is more about when he feels this team is going to make a serious run at a ring - and when does he think Herrera can deliver the type of production that Murphy already does? Because, if scouting reports say Herrera can be an All-Star, but not until 2016 or 2017 - at the same time Alderson feels next year and the year after are his window to contend with an affordable Matt Harvey and Zack Wheeler - then he needs to sign Murphy to an extension and trade Herrera in a package for more powerful bat. However, if Alderson truly doesn't think his team will get to October the next two seasons, if he thinks 2017-2020 is his window, then he should keep Herrera and trade Murphy in a deal for a powerful bat.
In either case, all eyes are on Herrera, since he may dictate how Alderson handles a variety of decisions this winter...
By the way, in this week's MetsBlog Q&ACast, presented by Verizon, I answers fan voicemails about Murphy, as well as Terry Collins's job status, Wally Backman and Frank Viola, injuries, luck and Wilmer Flores's value at shortstop...
