Hyatt (knee) was waived/injured by the Cowboys on Wednesday.
Hyatt had to be carted off the field Thursday, and, as evidenced by this news, the injury appears to be serious. Hyatt was only expected to supply a depth role in 2020 if he was to make the roster, and he'll revert to injured reserve if he goes unclaimed off waivers.
Hyatt was carted off Thursday's practice field due to an apparent knee or leg injury, David Helman & Rob Phillips of the Cowboys' official site reports.
Hyatt could challenge for a depth role along Dallas' offensive line if healthy, but he'll first need to determine the severity of his injury. Per Michael Gehlken of The Dallas Morning News, initial evaluations indicate that Hyatt could be in line to miss significant time.
