What happened: Chris Tanev will not return to tonight's game due to an upper-body injury. The Maple Leafs announced the early exit during the preseason matchup.

Why it matters: This marks another early health setback for Chris Tanev, who previously worked his way back into the lineup in September. His availability is critical for Toronto's defensive structure heading into the regular season.

What to watch: Toronto will evaluate the defenseman's status as the regular season approaches.
