Cleveland Browns quarterback Deshaun Watson has entered the NFL concussion protocol, according to reports from Fox News and ABC News, leaving the team's quarterback position unsettled.

ABC News reported that Watson was placed in the concussion protocol after experiencing symptoms Monday night. That report said Shedeur Sanders could go against the Saints. Its summary does not mention a helmet-to-helmet hit.

Fox News reported that Watson entered the protocol days after a helmet-to-helmet hit, and that the injury left the Browns scrambling at quarterback. Its headline described Sanders as a "possible starting QB" for the team.

The two accounts differ on how the injury developed. Fox News tied the protocol entry to a helmet-to-helmet hit that came before it, while ABC News said symptoms surfaced Monday night and did not mention a hit. Neither summary explains how the two timelines relate.

Neither Fox News nor ABC News gave a timeline for Watson's return to play in the summaries available. Neither report confirmed a final decision on who will start, though both named Sanders in connection with the team's quarterback plans.

Watson's availability and the team's quarterback decision remain open in both reports.
