08:07 AM ET 11.03 | Miami Dolphins rookie signal-caller Ryan Tannehill is officially listed as questionable for the team's game against first, overall pick Andrew Luck and the Indianapolis Colts this Sunday. However, the Dolphins and Tannehill have been openly optimistic for the rookie's availability for the matchup. Now, the Dolphins have received some potentially great news regarding their starting quarterback. Tannehill will be a game time decision on Sunday and ESPN's Ed Werder has called his chances to play in the game "better than 50-50." If Tannehill looks shaky in pre-game warm ups, Matt Moore will get the start for Miami. It has also been reported that if Tannehill begins to struggle during the game he will be pulled in favor of Moore for precautionary reasons.
