deGrom (back) will remain in Florida to throw a bullpen session Friday, Kristie Ackert of the New York Daily News reports.

Reports from earlier Thursday suggesting that deGrom may not travel with the team for at least Friday's game against the Indians have been confirmed. deGrom will remain at the team's spring training complex in St. Lucie to throw at least one bullpen session. Once deGrom gets through Friday's bullpen session, there should be more information one way or the other on whether he'll be able to return to the rotation or require a DL stint.
