The centre, one of the Kings' best players on faceoffs, has been sidelined with a suspected concussion since he was struck with an illegal hit to the head by San Jose's Raffi Torres in Game 1 of Los Angeles' second-round series against the Sharks.
Torres was suspended by the NHL for the remainder of the series.
Stoll has been skating with the team for several days. He had seven goals and 11 assists in 48 games in the regular season.
It was kind of touching. I didn't know really what to expect. I'm very appreciative and thankful for the people that supported me in my time here ... as I said, we'll move back to the area at some point in our life.
