New York Mets reliever Tim Byrdak will miss four to six weeks because of a knee injury and star third baseman David Wright has gotten a cortisone shot to help his ailing rib cage.
Mets general manager Sandy Alderson gave the injury updates Monday. The Mets were playing Detroit in an exhibition game.
Byrdak will have surgery Tuesday to fix a tear in his right knee. He pitched in 72 games last year and was expected to be the only left-hander in the Mets' bullpen when the season opens in April.
Wright has not played in a spring training game this year. He's been slowed by pain in his left rib cage and is in New York awaiting further treatment.
