Thornton was placed on injured reserve Sunday after experiencing swelling in the knee. But a day later, DeBoer said the issue stems from an infection and that the centre has been given antibiotics.
“He should be fine,” DeBoer told media, according to The Mercury News.
Thornton, 39, has battled knee issues over the past 17 months. He played in just 47 games last season and did not dress during the playoffs.
He didn’t join the Sharks on their four-game East Coast road trip and the club hasn’t set a timetable for his return to the lineup.
