Head coach Ron Rivera and general manager Dave Gettleman approved the league's decision to expand.
"I love it. I really do," Rivera said. "You can always use extra players. And it also bodes well for your future, in terms of developing guys. I think it's a plus. More guys get opportunities, more guys get chances to play. That's what you want. It's a great step."
Said Gettleman: "From a player development standpoint it's a plus, most definitely. This is competitive, and there are some guys that you have to let go that you don't want to. And (the expansion) is definitely a positive move for the players; it keeps them in the game."
Tuesday's practice was delayed for about 45 minutes due to heavy rain, but the Panthers returned to the field and tacked on two extra sessions to take advantage of time in the humidity.
"We'll make the best of it," Rivera said.
Rivera reiterated that he's not overly concerned about Blackburn's back issue, and the training staff will see how he feels Wednesday.
As for safety
"I think he's going to be fine," Rivera said. "Last year, we brought a guy in off the street in a week – Quintin Mikell was ready to go. I see Roman Harper in the same vein. He's a veteran guy who knows a lot of football. I think he's going to be OK. And the thing he has over Quintin is he was here for OTAs and minicamp."
