Mets left fielder Jason Bay had tests on his strained rib cage Wednesday in New York, and the team planned to wait until he returned to camp to decide whether he will start the season on the disabled list.
Bay felt discomfort on his left side Tuesday and was pulled from the lineup. He went to New York on Wednesday morning for tests and was scheduled to get back at night.
The Mets open the regular season on Friday night at Florida. The team told outfielder Lucas Duda he will make the 25-man roster if Bay needs to go on the disabled list.
Rosters must be set by 11 a.m. Thursday. If Bay goes on the DL, the move could be backdated so that he's eligible to play on April 9.
"We will make a decision on whether he is disabled in the immediate future here," general manager Sandy Alderson said. "I haven't had a chance to talk directly to Jason myself, so subject to that we can't make an announcement of any sort or reach a final decision."
It is still unclear whether the latest problem is related to the back stiffness that shelved Bay on Saturday and Sunday.
Nick Evans, who also would have been an option to replace Bay, cleared waivers and has accepted the team's decision to outright him to Triple-A Buffalo.
Infielder Luis Hernandez also cleared waivers but has 72 hours to decide if he will accept an assignment to Buffalo or become a free agent.
