It is not just Cleveland tight end Kellen Winslow and the rest of his teammates that are alarmed at the number of staph infections that have plagued the Browns. The NFL Players Association also has taken notice.

NFLPA interim executive director Richard Berthelsen wrote in an email Thursday that his group is attempting to get answers to a situation that has befuddled many. Six Browns are known to have contracted a staph infections in recent years.

“Of course we are concerned about it,” Berthelsen wrote. “Our medical advisor Tom Mayer has been in touch with league medical people to try to address it.”

How the issue is addressed remains uncertain. But clearly it is an issue that isn’t going away anytime soon.
