NEW YORK -- Left fielder Jason Bay was expected to rejoin the New York Mets on Tuesday, but will not due to illness.

Bay landed on the disabled list April 24 with a fractured rib on his left side, which he suffered on an attempted catch of Gregor Blanco's fly ball the previous day, in Game 2 of a doubleheader against the San Francisco Giants.

Bay served as a designated hitter the past two days for Class A St. Lucie. He had been due to play the outfield for the Florida State League club on Monday night to complete a rehab assignment.
