"It was one of the best days Desmond has had," Cash said. "So that's a good sign."
Jennings told the Sun Herald that his knee is "feeling good."
"Just trying to get back into action, get back into shape and get ready to play," Jennings said. " ... [My knee is] progressing. That's good. It definitely doesn't feel like it felt before. So we're still getting the last little bit of rehab in, then we'll go from there."
Jennings said his rehab schedule will be pieced together day by day, depending on the way the knee feels.
Asked when he would begin playing in rehab games, Jennings replied, "Tomorrow, I hope."
"But I don't know," Jennings said. "We'll see. As long as it keeps progressing, it'll be sooner than later."
Cash is hopeful both will be back soon.
"We still have a ways to go, but we're optimistic we're headed the right direction," Cash said.
