Sharks' Erik Karlsson: Questionable Tuesday

Karlsson (upper body) is in doubt for Tuesday's clash with the Red Wings, Curtis Pashelka of The San Jose Mercury News reports.

Karlsson has missed the Sharks' previous two tilts while dealing with his upper-body problem. While the veteran defender is goalless in his last six contests, he has picked up four assists over that stretch. If cleared to play against Detroit, Karlsson should retake his place on the blue line where he figures to offer top-half fantasy value.
