Calgary Flames captain Jarome Iginla did not skate with his teammates Sunday on the first day of training camp because of a groin injury.
General manager Jay Feaster told reporters it was a precautionary move. The Flames were also short center Roman Cervenka and defenseman Anton Babchuk.
Cervenka is not allowed to skate because he is still taking blood-thinning medication after dealing with blood clots while playing in the Kontinental Hockey League. Feaster said Cervenka will visit a specialist in the next week to determine when he can stop taking the medication.
A free-agent addition in the offseason, the Flames hope Cervenka can fortify what has been an ongoing problem for several seasons at center.
Feaster said Babchuk is expected to be out three weeks with a shoulder injury he incurred while playing in the KHL during the lockout.
