Rays general manager Matthew Silverman confirmed that Alex Cobb will be shut down for approximately a week because of tendinitis in his right forearm, and is no longer the starter for Tampa Bay on Opening Day, per the Tampa Bay Times.
Cobb left Tuesday's Grapefruit League game with the injury after tossing three perfect innings. He will be evaluated again after at least seven days of rest, and is not expected back in games until April at the earliest per the Tampa Tribune.
Silverman would not reveal his Opening Day plans, citing that he's more focused on putting a staff together, internally and externally. Manager Kevin Cash told reporters that there's a lot of moving pieces in the rotation, but he likes what he's seen out of Nathan Karns, Burch Smith and Matt Andriese this spring, per the Tribune.
