ALAMEDA -- When the Raiders took the field for practice Thursday it was a breezy day with temperatures inching into the 60s.
In other words, nothing to prepare them for the cauldron of heat and humidity that awaits them Sunday in Miami. The Dolphins, of course, choose to wear white, meaning the Raiders will be in their heat-retaining black jerseys.
The forecast is for temperatures in the mid-80s, humidity in the 70 percent range and a chance of thunderstorms.
There is little the Raiders can do about it except hydrate and maybe substitute a little more if possible.
In the opener each member of the starting defensive line played more than 40 snaps -- right end Matt Shaughnessy (48), defensive tackles Tommy Kelly (46) and Richard Seymour (42) and left end Lamarr Houston (46).
The main reserves, end Dave Tollefson and tackle Desmond Bryant, had 24 and 16 respectively. The Raiders are likely to increase their snaps and reduce those of the starters, while also using rookie Christo Bilukidi, who had nine snaps against San Diego.
"Obviously when you really take into account the Miami heat, we're going to have to do a good job with our rotation and keeping those guys fresh and keeping them where they'll be at their best in the fourth quarter," coach Dennis Allen said.
The Raiders, particularly those from southern home towns, aren't wasting a lot of time worrying about the heat.
"Man, I'm from Jackson, Mississippi," Kelly
Middle linebacker Rolando McClain, from Decatur, Ala., wasn't overly concerned, either.
"It's just hot. It's not like you died or anything," McClain said. "It's just a little sun. Drink some water, you'll be fine."
-- McClain, who missed practice Wednesday with an ankle injury, was on the field and going through drills, as was Taiwan Jones, who sat out the previous day with a rib injury.
-- Stefen Wisniewski opened with the first team for the second straight day during group drills.
-- Wide receiver Denarius Moore apparently bounced back without any issues a day after quarterback Carson Palmer said he made some "phenomenal" catches.
-- Practice squad long-snapper Nick Guess was working on field goal snaps on the far field with holder Shane Lechler and place kicker Sebastian Janikowski. Jon Condo, recovering from a concussion, was leaving the facility as practice began.
-- After a review of the coaches tape, rookie linebacker Miles Burris had his number of tackles increase from nine to 12.
