The Pittsburgh Steelers will be playing for their postseason lives when they take on the division-rival Baltimore Ravens in Week 18. If the Steelers best Baltimore, their season will continue. If they lose, they’ll enter the offseason earlier than anyone in Pittsburgh would have hoped.The good news for the Steelers is that they’ll be getting a major defensive weapon back for the matchup. After missing Pittsburgh’s last three games due to a partially collapsed lung, star defensive end T.J. Watt will be back out on the field on Sunday night.Heading into the critical contest with the rival Ravens, Watt is feeling healthy and confident after a productive week on the practice field, which is exactly what Steeler nation wants to hear."I feel pretty good. Honestly, don't know if I could have said that a week ago, but I feel really good,” Watt said, via ESPN. “Feel really confident about the week of practice and excited to play. "Like I said, I had a great week of practice. I had no limitations. Tried to simulate as much as I could with shoulder pads and stuff like that, but you can only simulate so much. So I feel really good right now. Hoping that's the case on Sunday as well."This story will be updated.
