SAN JOSE – The San Jose Sharks have their first notable injury of training camp, as veteran defenseman John Klingberg is now considered day-to-day with an upper-body ailment. Sharks coach Ryan Warsofsky said Klingberg sustained the injury in the Sharks’ 3-0 win over the Vegas Golden Knights on Sunday at SAP Center in the preseason opener for both teams. Warsofsky said it appears unlikely that Klingberg will be available Friday when the Sharks again host the Golden Knights. In January, Klingberg signed with the Edmonton Oilers and was part of the team’s run to the Stanley Cup Final in the spring. Klingberg signed a one-year, $4 million deal with the Sharks as a free agent in July.
