3:14pm: An MRI revealed a herniated disc in Urena’s back, Wells Dusenbury of the Sun Sentinel was among those to tweet.

1:07pm: Marlins right Jose Urena is hitting the shelf for the foreseeable future, with the club announcing that he’s going to the 60-day injured list. Urena is said to be dealing with a left lower back strain.

It’s a bit of a surprising turn of events for the starting pitcher, who had been scheduled to start on Wednesday before hitting the 10-day IL. At the time, there wasn’t much indication that he’d be sidelined for a lengthy stretch. The injury is evidently more severe than is apparent from the basic description of a lower back issue.

Given the timing, Urena won’t be eligible to return from the IL until mid-August. That all but eliminates him as a summer trade target. The 27-year-old hadn’t been in top form, with a 4.70 ERA in 74 2/3 innings, but he turned in consecutive sub-4.00 ERA campaigns in the prior two seasons. With his steady mid-to-upper nineties fastball velocity, Urena could have been an interesting swingman for the right contender.

Urena is earning $3.2MM this year as a 3+ service-class arbitration player. That leaves two more arb-eligible campaigns to come. The injury will sap his ability to procure a significant raise next fall, so it’s still plausible to imagine the Marlins tendering him a contract. Whether that’ll be a sensible approach will depend upon Urena’s recovery and showing upon his return,

This move represents the corresponding 40-man roster transaction for the club’s previously reported decision to select the contract of Yadiel Rivera. He’ll help fill in for Martin Prado while the veteran infielder is sidelined.
