But there's no firm date for Crosby's return, Bylsma said.
"The schedule with Sidney, we thought he would return sometime this week. There wasn't a definite date or definite day," Bylsma said at practice. "Right now, I haven't had a lot of contact. He's in contact with our trainer just to let him know how he's feeling and so forth. There really isn't a timeframe, as far as we're concerned at this point, of getting him back into town."
Crosby left the team last week to visit his parents outside of Halifax, Nova Scotia.
Since he left, not only did Pittsburgh lose to the Washington Capitals, 3-0, on Sunday, the Penguins lost Malkin to two torn ligaments in his right knee. Malkin was injured in the Penguins' 3-2 win over the Buffalo Sabres on Friday. It's still not clear if he'll need surgery.
"Given the severity of the injury, right now we're taking some time to let his knee calm down a little bit, get doctors' opinions and options for what he has going forward," Bylsma said of Malkin. "It's not a lot of urgency, at this point in time, to rush into a certain decision."
Meanwhile, the cloud continues to hover over Crosby, who hasn't played since an 8-1 win over the Tampa Bay Lightning on Jan. 5. Bylsma was asked Monday about the possibility of Crosby's absence growing even longer than originally thought.
"That really has not been a topic of conversation or a thought. Certainly, when the doctor told us he had a mild concussion, we were expecting this not to last this long and it was certainly our concern about making sure his health is full when he comes back to play," he said. "But really, we haven't gone down a label of time. We certainly want to make sure we go through the necessary steps, and he gets returned to health and he's symptom-free and then progressing toward what the doctor recommends with exercise and so forth."
Letestu will miss four to six weeks following surgery on his left knee. He suffered a meniscus injury during morning skate last Tuesday, prior to a 4-3 shootout win over the New York Rangers.
