Pregame in Denver: Sights and sounds

DENVER -- A feel for the pre-game scene from Invesco Field at Mile High, where the Patriots visit the Broncos today (4:15 p.m.)

Weather conditions: After snowfall in Denver Saturday, there is no snow expected today. However, there is snow awaiting spectators at their seats in parts of the stadium. It is currently 31 degrees and cloudy. By kickoff, the projection is for the temperature to rise to the mid 40s, with the possibility that the sun peeks out. There is no snow on the field, which was covered with a tarp.

Officiating: Carl Cheffers' crew will work today's game. Four games into the season, some officiating trends start to emerge, and ESPN.com NFC West reporter Mike Sando charts them in his "officially speaking" blog entry. For example, Cheffers' crew has only had two coach-initiated challenges this season.

50th anniversary celebration: The teams will be in their throwback uniforms as part of the season-long celebration of the 50th anniversary of the American Football League. The Patriots will wear red and white uniforms, replicating the ones worn by the 1963 team that claimed the franchise's first division title and competed in the team's first league championship game. The Boston Patriots hosted the AFL's first regular-season game on Sept. 9, 1960 at Boston University Field. Gino Cappelletti (Patriots) and Gene Mingo (Broncos), who played in that game, will be part of the opening coin toss.

TV broadcast: Jim Nantz (play by play) and Phil Simms (analysis) will call the game on CBS. This is scheduled to be their second of four straight Patriots broadcasts.

Scouts in the house: As is regularly the case, pro scouts from both teams' next opponents are scheduled to be in attendance, which means the Titans and Chargers are represented. The Patriots host the Titans on Oct. 18, while the Broncos visit the Chargers that night.

Today's plan on the blog: Teams must declare their inactive players 90 minutes before kickoff. The plan will be to pass along the inactive players around that time, followed by what that means for others on the roster. At halftime, there will be an analysis on the first 30 minutes. At the conclusion of the game, there will be a quick recap, followed by sights and sounds from the post-game locker room. ESPN.com national sports columnist Gene Wojciechowski and ESPN.com AFC West reporter Bill Williamson are also present.
