Dan Caesar of the St. Louis Post-Dispatch reports how Sunday will be a vastly different day for Howie Long:

Howie Long spends his fall Sundays in the Fox Sports compound in Los Angeles, working as an analyst on the network’s NFL studio show.

But this Sunday, he plans to be about 1,800 miles to the east, in St. Louis for an interesting football family reunion. Long, who had a Hall of Fame career as a defensive end with the Raiders, will be in town to watch the first matchup in the pros between sons Chris and Kyle. Chris is in his sixth year as a defensive end for the Rams. Kyle is a rookie offensive guard for the Chicago Bears, who face the Rams at noon.

Dad sees his sons play in person when they have a weeknight game, and there is no mistake as to the team he is rooting for then. But this situation is much different, as they not only will be on the field at the same time but figure to be going against each other at times.

“I’m sure there will be some range of emotions,’’ dad said this week. “I’m not sure what that will be, we’ll have to see when we cross that bridge. … It’s exciting. It’s scary. It’s a lot of different emotions.’’

Meanwhile, back in LA, Randy Moss will sit in for Long on Fox NFL Sunday. It could be an audition of sorts for Moss, who has been outspoken in his new studio role for Fox Sports 1.
