I would put Tyron's future within the following probabilities:
10% - Tyron announces his retirement before the end of the season.
20% - Tyron does not perform well during his 21 day practice window and is placed on Injured Reserve, missing the entire season.
10% - Tyron is activated but they still want to wait a few weeks for him to be 100%. He goes through limited practice for a few weeks but does not play.
10% - Tyron is activated and slowly integrated back into the starting unit. He starts off with certain packages in a limited role.
30% - Tyron is activated and instantly starts at LT while Tyler is switched to LG. However, at some point in the regular season Tyron goes down again. The Cowboys are forced to put Tyler back at LT after playing LG for a number of games. McGovern, who hasn't played LG for that same number of games goes back into LG.
20% - Tyron is activated and instantly starts at LT for every remaining game for the Cowboys.
