Carolina Panthers middle linebacker Jon Beason, who suffered a season-ending torn left Achilles' tendon in Sunday's loss to Arizona, tweeted that he was undergoing surgery to repair the injury on Friday.
"Well I'm here about 2 go under for surgery," Beason tweeted. "Temporary setback for a permanent comeback."
Beason, who was placed on injured reserve Wednesday, had surgery two weeks before the season opener to alleviate inflammation in his left foot. But he wrote on his blog Tuesday that he doesn't believe he rushed back too soon.
"If I had to do it all over again, and go into that game with my Achilles injury, I would," Beason wrote. "Because football defines who I am. Sometimes you have to do something that you've never done to get something you've never had. The motivating factor is simple for me. To win, and not fear failure.
"A lot of people say, hey, he rushed back too soon. But actually, I didn't. I told my teammates and myself that I would only play if I could help the team. I felt ready to do that. Myself and the Panthers' medical staff were convinced that I was healthy enough to play in the opener versus the Cardinals."
To help bolster their defense, the Panthers reached a deal with veteran nose tackle Ron Fields on Tuesday.
