Urena (forearm) was designated for assignment Monday, Craig Mish of SportsGrid.com reports.
He was the team's longest tenured player, and Mish reports the Marlins were originally going to non-tender Urena on Wednesday. Instead, they cast him off the 40-man roster to make room for the newly acquired Adam Cimber. Urena fractured his forearm in late September and is questionable for the start of spring training.
