Pittsburgh Penguins goaltender Tomas Vokoun was released from a hospital on Wednesday after having a procedure to dissolve a blood clot in his pelvis.
Penguins coach Dan Bylsma is unsure when Vokoun will be able to return to the ice.
The 37-year-old Vokoun noticed swelling in his thigh after a Saturday morning practice and went to a hospital, where the blood clot was discovered and immediately removed.
Vokoun has dealt with blood clots before. In April 2006, he was diagnosed with a rare blood condition that causes multiple clots, forcing him to miss the rest of the regular season and the playoffs.
To add depth during Vokoun's absense, the Penguins signed Jeff Deslauriers to an AHL tryout deal.
Marc-Andre Fleury is the Penguins' No. 1 goaltender and Jeff Zatkoff likely will be the backup until Vokoun returns.
Vokoun joined the Penguins last season and played in 20 regular-season games as Fleury's backup. The veteran also stepped in during the playoffs when Fleury struggled and he helped the Penguins reach the Eastern Conference finals.
Vokoun finished the 2012-13 regular season with a 13-4-0 record, a .919 save percentage and 2.45 goals-against average for the Penguins. In 11 postseason games, he had a 2.01 GAA and a .933 save percentage.
