Burnett leaves ill; Watson confirms surgery

ALAMEDA, Calif. – Oakland Raiders linebacker Kevin Burnett left practice early Thursday due to illness and was officially listed as “limited” for the day.

As for the rest of Oakland’s injury report, four players did not participate, and none was a surprise – tight end David Ausberry (shoulder), strong safety Tyvon Branch (ankle), left guard Lucas Nix (ankle) and left tackle Menelik Watson (knee). None of the four is expected to play Monday night in Denver.

A day earlier, though, Watson confirmed he had undergone surgery on his right knee, saying he initially injured it in the week before the final preseason game. The knee swelled and then locked up in practice on the Wednesday before the season opener at Indianapolis, he said, and surgery ensued.

“It’s not that bad,” Watson said on Wednesday. “It’s not an ACL or anything.”

ESPN NFL Insider Adam Schefter had reported the procedure was arthroscopic surgery on a lateral meniscus and that Watson was expected to be out a month, but Raiders coach Dennis Allen would not comment on the exact nature of the injury.
