Thing is, we have no idea why. It's as crazy me saying he is already 100% and ready to play. We don't know, so making conclusions like this without doctors coming out and saying there actually has been an issue, makes no sense.
The only thing we know for sure is, that the statement says there have been no set backs, and Tua's parents are adamant that Tua will be the starting QB for the Dolphins in 2023...That at the very least does not tell me Tua has been having issues with the past two concussions from this past season.
