Weaver has taken anti-inflammatories but did not receive a cortisone shot for the knee, which he said has showed signs of improvement, but not consistently.
"It's back and forth," said Weaver, who turns 34 on Aug. 22. "Achy at times, not at others, but it's better than it was. Treating it and hopefully the irritation goes down."
Weaver said a potential rehab assignment was still being discussed, although he feels it may not be necessary.
"Simulated games or something like that would probably suit just fine," he said.
