The Boston Globe has learned from team sources that catcher Jason Varitek will have arthroscopic surgery for cartilage damage on the left knee he injured in the second inning of Monday night's game.
The team later announced that the captain has been placed on the 15-day disabled list effective today because of a knee injury and will release more details on his status after tonight's game.
The team purchased the contract of Ken Huckaby from Pawtucket.
Varitek appeared to sustain the injury last night when he hit the second-base bag awkwardly while advancing from first to second on Crisp's single in the second inning, but his knee may have been bothering him for a couple of weeks.
In other roster moves, the team recalled righthanded pitcher Jason Johnson from Triple-A Pawtucket of the International League, who is making his first start with the team since July 5.
The team aslo designated first baseman Hee-Seop Choi, who was on option to Pawtucket, for assignment and optioned pitcher Javier Lopez to Pawtucket.
