The Detroit Lions are opening the practice window for rookie quarterback Hendon Hooker.

Hooker tore his ACL last November while at Tennessee.

Despite the injury, the Lions took Hooker with the No. 68 pick in the 2023 NFL Draft.

Dan Campbell said that a big reason for opening his practice window is for the team to start building him up. 

"Yeah, by rule we can't coach him, so that's why," Campbell said. "I mean we can't -- we can have him in meetings, but he can't be out there and going through any fundamental work. You've just got to kind of stand there. So, that's where it helps, to be able to actually do individual work with him, have him take a snap. That's why it's big. I mean it'd be nice to just do some of those things with him, but that's why you've got to get him on the roster. Otherwise, rules don't allow for him to do any of that."

The Lions will now have 21 days to activate Hooker onto the 53-man roster. If they do not, they'll revert to injured reserve for the remainder of the 2023 season.
