Concerned about Michael Olowokandi's and Mark Madsen's availability because of injuries, the Timberwolves on Tuesday called up rookie center Dwayne Jones from their affiliate in the NBA Development League.

Jones, 22, a 6-11 free-agent addition last summer from St. Joseph's, is expected to join the Wolves in time for their game tonight against the Seattle SuperSonics, possibly even for the shootaround this morning at Target Center.

Jones averaged 9.7 points, 11.6 rebounds and 28.9 minutes in 10 appearances for the Florida Flame, the minor-league team that serves as the affiliate for Minnesota, Boston, Miami and Orlando. He ranked second in the D-League in rebounding and first in offensive boards (4.9).
