Thornton (shoulder) was on the ice for morning skate and could be a lineup option for Saturday's game against the Rangers, Kevin Kurz of CSN Bay Area reports. Thornton centered the Sharks' top line during morning skate, an indication he's ready to return after a four-game absence. Since he's still listed on the Sharks' injured reserve list, his availability remains a question mark for now, but fantasy owners will surely want to keep tabs on his status throughout the day.
