Dustin Penner was back in the lineup last night after being a healthy scratch in the two previous games.
Penner has four points through his first 16 games and was called out publicly by MacTavish for his lack of work ethic on Sunday.
"It's up to me to try and do what they ask of me," Penner said prior to yesterday's game. "I have to make a committment to play a better overall game."
Penner was relegated to the press box and watched the Oilers lose at home to the Avalanche, and on the road to the Detroit Red Wings.
"It's definitely tough watching your teammates out there when you can't be part of it," Penner said.
"But you do notice a lot of different things that you probably wouldn't have noticed if you weren't up in the press box."
