Detroit Pistons center Isaiah Stewart has been dealing with a calf injury that has been getting progressively worse, according to head coach J.B. Bickerstaff. The team will take time to allow the injury to heal, which could mean an increased role for rookie Jalen Duren in the meantime.

Why it matters

Stewart has been a key defensive presence and enforcer for the Pistons, so his absence could be a major concern for the team as they look to maintain their position atop the Eastern Conference standings. The Pistons will need to rely on their depth to weather the potential loss of Stewart.

The details

Bickerstaff said Stewart "gutted it out" in the team's last game but was clearly favoring the injured calf late. The team will now take time to allow the injury to fully heal rather than rushing Stewart back. In his absence, rookie center Jalen Duren could see an uptick in minutes to help fill the void left by Stewart's defensive presence and physicality.

  • Stewart has been dealing with the calf injury for some time.
  • The injury worsened in the Pistons' most recent game.

What they’re saying

“It's something he's been dealing with. It just had been getting worse. He gutted it out last game and I think you could see he was favoring it late … it's something we're going to take time with.”

— J.B. Bickerstaff, Head Coach, Detroit Pistons (The Detroit Free Press)

“I would just say I'm just very competitive and I view the court as like us going to war. I know the other team is trying to take our heads off. So, it's just like a flip, like I got something to defend. I just got pride. I'm not going to lay down and let you have an easy game.”

— Isaiah Stewart (The Young Man and The Three Podcast)

What’s next

The judge will decide on Tuesday whether to allow Walker Reed Quinn out on bail.

The takeaway

This injury to Isaiah Stewart is a major concern for the Pistons, as he has been a key defensive anchor and enforcer for the team. His absence could put more pressure on the team's depth, especially rookie Jalen Duren, to step up and fill the void left by Stewart's physicality and intensity.
