CHARLOTTE, N.C. -- The last time Carolina Panthers linebacker Thomas Davis showed the world his broken right arm, it was a gross image of wrinkles and stitches after his team lost in the Super Bowl.

On Monday, he showed his arm -- it still has the metal plate in it -- to the assembled media, revealing a scar that looked much better as he participated in voluntary workouts that opened Monday.

"The arm is doing really well," said Davis, who suffered the broken forearm in the NFC Championship Game and underwent surgery the next day. "I'm excited about where I am now opposed to where I was a few weeks ago. I'm excited about being able to lift [weights] again and regaining the strength I need to play this game.

"It was a while where I couldn't even really lift my daughter without feeling the pain in my arm."

Another player happy to participate in Panther workouts was wide receiver Kelvin Benjamin, who missed the entire 2015 season because of a torn ACL in his left knee. He said he is progressing on schedule and should be ready for training camp in the summer.

"I can't wait to get to training camp," Benjamin said. "I'm looking forward to it. I'm actually counting days."

Benjamin caught 73 passes for 1,008 yards and nine touchdowns in 2014.

"I'm still limited to a lot of things," Benjamin said. "I'll probably do individuals with the team. ... I pretty much can run all the routes. We're just not rushing it. We've got time."

Davis also said he has had to temper what he can do. He said he has to remind himself sometimes when he is doing things that doctors said he shouldn't be doing yet.

As far as the photo, Davis said he wanted people to see just how far he was willing to go to play in the Super Bowl.

"A lot of people questioned the reason for me putting the picture out there, but it was strictly just to show people what I'm willing to do for my team, what I'm willing to do for this organization, for this city," Davis said.

One thing Davis hasn't done -- he hasn't watched a replay of the 24-10 loss to Denver in the Super Bowl.

"I lived it, so I don't need to watch it," said Davis, who had seven tackles in the Super Bowl. "Defensively, we watched the plays and what we did defensively. And that's pretty much what we do with any game."
