After the Pittsburgh Penguins defeated the Tampa Bay Lightning 5-3 last night at the CONSOL Energy Center, head coach Dan Bylsma announced that Penguins center Evgeni Malkin had suffered short-term memory loss and was officially diagnosed with a concussion. Although Malkin’s memory is coming back, he will not travel with the Penguins on their three-game road trip. Bylsma also denied a previous report that Malkin had been experiencing headaches and disorientation. The only symptom Malkin has suffered is the short-term memory loss, which is nothing to fool around with. Malkin received the concussion after getting slammed after colliding with Florida defenseman Erik Gudbranson at full speed on Friday night.
