Monday morning was a steamy one at the Detroit Lions training camp. A packed house of eager fans encouraged the players through a sweaty session that featured a lot of the team's primary standouts asserting themselves.

ALLEN PARK — The Detroit Lions’ training camp has seen its share of high-profile visitors in recent years, and Monday was no different, with a former Super Bowl-winning coach in attendance. Lions offensive coordinator John Morton told reporters that former Raiders and Buccaneers head coach Jon Gruden would be attending Monday’s practice.

After a pretty solid start to training camp, Hooker retains a strong lead on the backup job. That said, Allen was actually the backup on Day 1 of camp and has done a pretty nice job throughout practice as well. That wasn’t enough to earn any votes, but Thursday’s preseason game could shake things up.
