A potentially lethal staph infection was diagnosed in a third Tampa Bay Buccaneers player this week the team acknowledged Friday.

The latest discovery came on Thursday the same day left guard Carl Nicks learned he had a recurrence of his initial MRSA infection. Nicks and kicker Lawrence Tynes were diagnosed with MRSA infections in August.

MRSA is a type of staph bacteria that is resistant to several antibiotics.

Despite the two discoveries this week an infectious disease specialist flown in by private jet to meet with Bucs players and staff members said Friday he thinks the team’s training facility remains a safe work environment for all employees.

“I believe it is a safe environment for players and staff and I think there are a few reasons why this is the case’’ said Deverick J. Anderson the co-director of the Duke University Infection Control Diseases Outreach Network (DICON).

“I got to come and review the facility about a month ago and I got to see how practice was performed and I think that based on my observations there wasn’t anything to (indicate) they are at a very high risk.

“I think football in and of itself is a high risk factor for MRSA infections in general but the fact that a case — and now two and three cases — have occurred does not necessarily mean there is any higher risk here than at any other football location in the country.’’

Citing medical privacy laws and requests from the player Bucs general manager Mark Dominik declined to name the third Bucs player to contract MRSA.

Multiple online reports citing unnamed sources identified the player as rookie cornerback Johnthan Banks.

A second-round pick in the 2013 draft Banks was not at practice on Friday and was listed as “questionable” on the team’s official injury report for Sunday’s game against Philadelphia with an “illness.’’ Banks did not appear on the injury report the previous two days.

Nicks and kicker Lawrence Tynes were diagnosed two weeks during the preseason with methicillin-resistant Staphylococcus aureus (MRSA).

Tynes’ infection has so far proved to be the most severe. Unlike Nicks who declared himself “MRSA free’’ on Sept. 11 and played in the team’s past two games Tynes is out for the season.

The Bucs agreed to pay Tynes’ $840000 salary for this year but their decision to place him on the Non-Football Injury list sparked a grievance which was filed last week by the NFL Players Association on Tynes’ behalf. The grievance seeks to have the NFI designation lifted in part because it prohibits Tynes from receiving certain benefits including a year NFL of service toward his pension.
