Karlsson (thumb) was on the ice for Monday's practice session, Curtis Pashelka of The San Jose Mercury News reports.
EDGE Analysis
Karlsson doesn't seem to be significantly limited by his thumb problem and could be in the lineup for Tuesday's preseason tilt against the Kings. Last season saw Karlsson post his lowest point total (22) since the 2012-13 campaign, when he was limited to just 17 games.
