During the team's Friday morning workout, Louisville senior tight end Keith Towbridge displayed no lingering signs from surgery to repair an injured toe that sidelined him during the team's spring practice.
Joining a large group of teammates, he spent nearly an hour lifting weights, followed by 30 minutes working in a sandpit in the hot sun.
"Being out in the sun is tough," Towbridge told Cardinal Authority immediately following the grueling workout.
"We ring the bell every day. We all come out to work because we know what's in stake for latter in the season. We're all trying to reach the same goal and come together as a family."
Friday's workout caps the week that includes varying conditioning. On Tuesday and Thursday, the tight ends spend 90 minutes with the skill position players, further improving their comfort and understanding with the quarterbacks and routes.
"Like I tell everybody, 'you have to have a dog mindset to play this game'," he said.
"We do this everyday, with or without the cameras," he said. "There's really nothing to it, you just have to come out here and grind."
With the start of fall camp rapidly approaching and the start of the season about two months away, Towbridge, who started seven games last fall, said the focus will remain on becoming a stronger team and picking up where they left off left.
"Basically gel as a team," he said, adding that the offense will look to "get back on track and finish what we started last season."
The Cardinals will open the regular season at Papa John's Cardinal Stadium on September 1 when it hosts Charlotte.
