The Phillies say he'll start the season in the disabled list.
According to phillies.com, Phillies general manager Ruben Amaro Jr. essentially said Thursday Utley is sidelined indefinitely with patellar tendinitis, chondromalacia and bone inflammation in his right knee.
"We haven't seen him on the field yet and we're a week away," Amaro said. "It's likely he's not going to be making our club, at least not right now."
Amaro said Utley will accompany the team to Philadelphia on Monday.
"I think he feels better. We'll see. It's kind of a long-term process. It's not going to happen overnight," Amaro said.
