Ludvig (upper body) was loaned to AHL Wilkes-Barre/Scranton on Sunday for conditioning purposes.
Ludvig, who hasn't played since Dec. 31 against the Islanders, will get some playing time at the minor-league level and could be back with Pittsburgh after the All-Star break. The 23-year-old defender has one assist, 12 shots on goal, 23 blocked shots and 37 hits in 19 NHL outings this campaign.
