Hertl will undergo a surgical procedure to clean out loose cartilage in his left knee and is expected out for at least "several weeks". Hertl last played on January 27th and sat out for two games before participating in the All-Star game. The Sharks have not played since and announced on Monday that Hertl will undergo a surgical procedure on his left knee that will keep him out of the lineup for several weeks. Hertl had 15 goals, 34 points, 113 SOG, 22 PIMs and a -26 plus/minus in 48 games before his injury. With Mikael Granlund nearing a return, offensive responsibilities will fall heavily on him and Logan Couture.
