So, Cobb always has been tough. And maybe a bit stubborn.
"The hardest part for me is I'm a tough guy, I want to be on the field," the Green Bay Packers' do-it-all star said.
"I don't like missing practice. I hate missing practice. So, trying to be smart and be tough at the same time is difficult for me, but I understand that I have limitations and I have to be smart about it. But it's hard and difficult at times."
Cobb, his right bicep wrapped in kinesio tape, seemingly ran his routes like nothing was wrong, and he caught two passes during the end-of-practice no-huddle drill. However, on the way back to the huddle or sideline, Cobb jogged with his right arm kept close to his chest.
While the injury was apparent to the reporters on the sideline, neither coach Mike McCarthy nor the training staff pulled Cobb off the field.
"Every injury is different. Every player is different," McCarthy said. "Really, the process is always the same. They go through the evaluation with the medical staff. Their relationship with the medical staff is important because the communication from the individual to the doctor is a big part of the diagnosis. In Randall's case, we wouldn't put him out there if we thought he was in jeopardy of moving forward and getting healthy. But every case is different. There's a lot of time that's spent between the doctors, the trainers, Ted Thompson then to myself. It's something that a lot of time is spent and, frankly, it's not one of my favorite things to do because it is very time consuming during the mornings. So in Randall's case, it's probably something he's going to be battling for a while."
Cobb did not play in Friday's preseason contest against Arizona after being extremely limited in the two practices before the game.
Cobb is arguably the second- or third-most important player on the team behind Aaron Rodgers and, perhaps, Clay Matthews. He led the team in receptions and receiving yards last season, and set a franchise record for total yardage. Still, Cobb saw his difficult day as part of his training.
"I know at some point during the season I'm going to be in pain and I'm going to have to play and I'm going to have to be productive when I do play," Cobb said. "So, trying to push through right now is more of a mind-set for me. It's nothing to be worried about. I may look like I'm in a lot of pain -- and I may be in a lot of pain -- but I'll be fine."
Cobb said he sustained the injury during the Family Night Scrimmage. He jokingly said – or perhaps it was half-jokingly said -- that McCarthy was "probably looking for me right now" to discuss the injury and come up with a plan for at least the next couple days and Saturday's preseason game at St. Louis.
"There's a line between being tough and being smart, and I think us collectively together, between the coaching staff, myself and the training staff, we have to figure out what that line is," Cobb said. "We're playing with it right now. I've got to take it upon myself personally to be smarter with my communication with the coaching staff."
New injuries: NT Ryan Pickett (personal).
An ambulance was called to Pickett's house before practice so he was attending to a family matter. Apparently, everything is fine.
"Thanks for all the prayers, God is good!! My baby is fine. Still at the hospital should be leaving soon!" Pickett said on Twitter.
Old injuries: WR Charles Johnson (knee), S Sean Richardson (neck), CB Casey Hayward (hamstring), CB Tramon Williams (knee), G T.J. Lang (back), OL J.C. Tretter (broken ankle), LT Bryan Bulaga (knee), OT/G Andrew Datko (concussion); OT Derek Sherrod (leg), TE Andrew Quarless (quad), TE Ryan Taylor (knee), WR Jordy Nelson (knee), DE Datone Jones (ankle); DE Jerel Worthy (ACL).
Back from injuries: WR Kevin Dorsey (hamstring), RB Eddie Lacy (hamstring).
"DuJuan Harris is ready" to play on Saturday, McCarthy said. "I might not be as ready as he is. I think it's important to see how he feels tomorrow. First time he's had the pads on. He's classified as limited, and really Eddie was put in the limited category today. See how they respond after their evaluation in the morning will be a big indicator on how much work they get tomorrow."
