With 6:50 remaining in the 3rd quarter of Thanksgiving's Texans-Lions game, Texans running back Justin Forsett received a handoff at the Texans' 14-yard line and appeared to have been downed by contact at the 26-yard line. Instead, officials kept the play alive and Forsett ran—largely uncontested—downfield and scored Houston's third touchdown of the game. Replays indicate Forsett's left knee had contacted the ground concurrent with contact by Lions free safety Louis Delmas. After the touchdown was scored and prior to the expected booth-initiated instant replay review, Lions coach Jim Schwartz threw his challenge flag, effectively eliminating the booth review that could have reversed the call of touchdown.
NFL Rule 15-9 states that a coach/team is permitted a challenge except for plays when, among other circumstances, the on-field ruling results in a score for either team. The reason for this is because the booth's replay official is given the responsibility of initiating instant replay review for all scoring plays. This clear delineation of responsibility (coach vs. replay official) is meant to answer the question "is a team responsible or liable to lose a timeout/challenge if after review of a scoring play, the call is NOT overturned?" by simply taking away the team's ability to challenge such a call. If the team doesn't or cannot challenge, it's not liable.
Accordingly, Schwartz was prohibited from challenging the aforementioned play and his initiating a challenge in this situation ran in contrast with the Rules, the penalty for which is a loss of 15 yards.
Rule 15-9 also specifies that the booth replay official cannot initiate a review of a ruling against a team that commits a foul that delays the next snap. The purpose of this penalty is to disallow the booth from rewarding a team with a replay if a team deliberately wastes time in an effort to give the replay official more time to "think it over." A dead ball 15-yard penalty is, by rule, a foul that delays the next snap; therefore, the booth was prohibited from initiating the instant replay review process after Schwartz's illegal action.
This illegal throwing of the challenge flag therefore effectively prevented the call from being overturned by eliminating the booth's ability to initiate an instant replay review of the play and resulted in a 15-yard unsportsmanlike conduct penalty for this violation. The Texans ultimately won the contest in OT, 34-31.
