their broadcast booth. Sideline reporters are often granted inside information about an important update, such as injury, because they have the credentials necessary to do so. In cases of big events, teams consisting of many sideline reporters are placed strategically so that the main commentator has many sources to turn to (for example some sideline reporters could be stationed in the dressing room area while others could be between the respective team benches). In the United States, sideline reporters are heavily restricted by NFL rules; in contrast, both the 2001 and 2020 incarnations of the XFL featured sideline reporters in a much more prominent role. In motorsports, it is typical for there to be multiple pit reporters, covering the event from along pit road. Their responsibilities include covering breaking news trackside, probing crew chiefs and other team leaders about strategy, and commentating on pit stops from along the pit wall. On occasion in motorsport, the reporter on the sideline is an understudy to the lead commentator, as Fox NASCAR has used this tactic numerous times based on the career of Cup lead Mike Joy, a former pit reporter. Those who made the switch included Steve Byrnes (Truck Series, 2014), Vince Welch (Truck Series since late 2015), and Adam Alexander (did Cup for Fox-produced TNT broadcasts from 2010–14, Xfinity on Fox since 2015) did the same too. Sports presenter/studio host In British sports broadcasting, the presenter of a sports broadcast is usually distinct from the commentator, and often based in a remote broadcast television studio away from the sports venue. In North America, the on-air personality based in the studio is called the studio host. During their shows, the presenter/studio host may be joined by additional analysts or pundits, especially when showing highlights of various other matches (e.g. in 1985, Jim Nantz was the studio host for The Prudential College Football Report in Studio 43 in New York for CBS Sports, and during his four-year tenure there [the 1985 through 1988 college football seasons], he had Pat Haden [in 1985] and Ara Parseghian [in 1987 and 1988] as his co-hosts/pundits). Other roles Various sports may have different commentator roles to cover situations unique to that sport. In the 2010s, as popularized by Fox, American football broadcasts began to increasingly employ rules analysts to explain penalties and controversial calls, and analyze instant replay reviews to predict whether a call will or will
