The Buffalo Sabres sent defenseman Jordan Leopold to the St. Louis Blues in exchange for conditional second-round and fifth-round selections in the upcoming draft on Saturday.
The 30-year-old blueliner registered two goals and six assists in 24 games for the Sabres this season, following a two-year stretch with the franchise that saw him strike for 23 goals and 59 points in 150 appearances.
A second-round selection of Anaheim in 1999, Leopold made his NHL debut in 2002 for Colorado.
In 610 games over 10 seasons, Leopold has totaled 65 goals, 202 points and 268 penalty minutes.
Earlier on Saturday, the Blues assigned goaltender Jake Allen to Peoria of the American Hockey League.
The 22-year-old native of New Brunswick appeared in 12 games with St. Louis, going 8-3-0 with a 2.45 goals-against average.
