"I asked somebody if he's all right to play and he said, 'Yeah, I'm playing,'" Oilers coach Dave Tippett said. "You get a bruise on your knee, especially with him, there's extra precautionary stuff, but as far as I know, it's nothing serious."
McDavid went into the boards after being checked by Predators defenseman Dante Fabbro at 3:58 of the second period. The center iced the knee between periods, played 5:47 in the third and was on the ice at the buzzer. He played 19:27 over 20 shifts in the game, fewer than the 22:07 over 21 shifts he was averaging this season.
"He's got a little bruise on top of his knee or something like that," Tippett said. "They looked at it between periods, he iced it and they wanted to ice him right after the game again. I asked him, 'How are you doing?' and he goes, 'I'm playing. I'm fine.' That was the last I heard of it."
McDavid did not speak to the media after the game. The Oilers captain had multiple tears in his left knee and a broken tibia after hitting the goal post during the final game last season, and he revealed last month that he declined to have surgery in order to be able to play this season.
"You never want to go through a surgery -- I'm not going to call it risky -- but there were a lot of questions," he said Jan. 25. "It's not like it's an ACL where doctors can almost do that in their sleep. It's a PCL. Only a few doctors have done that, and it's not like it's been mastered."
McDavid had an assist Saturday and has 81 points (30 goals, 51 assists) this season, four behind teammate Leon Draisaitl (31 goals, 54 assists) for the NHL lead. The Oilers next play Tuesday against the Chicago Blackhawks.
