ALLEN PARK, Mich. – A daily review of the hot topics coming out of Detroit Lions training camp.

• The news of the day arrived before practice, when defensive end Ezekiel Ansah was pulled off the PUP list and returned to practice on a limited basis Tuesday evening. He didn’t fully participate and was not expected to, but he looked fairly strong during individual drills, pushing the sled with some gusto. He appeared happy to be back as well, and he’ll be eased into this since the Lions have a few weeks before their first regular-season game against the New York Giants. He’ll likely get some work during a preseason game, but it won’t be Friday as he’s already been ruled out. Right guard Larry Warford, who missed practice Monday, also returned Tuesday.

• The other major defensive line storyline revolved around defensive tackle Nick Fairley, who played with the second unit for the second consecutive practice. Ndamukong Suh and C.J. Mosley took the first-team reps at tackle throughout the practice, including during 11-on-11 periods. When Mosley wasn’t in, Jason Jones moved inside to take some reps at tackle. Fairley worked with Andre Fluellen and Jimmy Saddler-McQueen on the second unit a bunch Tuesday night and didn’t look all that impressive. In one-on-one drills with offensive linemen, he was blocked well once by Rodney Austin, but Fairley annihilated Austin the next time the two faced each other.

• Mosley, meanwhile, looked good with the first unit. He plugged the middle of the line well and didn’t lose any rushers when they came near him. In all, the first-team defensive line had another really strong performance against the first-team offensive line. Suh continues to look like his dominant self and Devin Taylor is getting better coming off the edge. It’ll be interesting to see what happens when Ansah returns to full strength and Taylor is truly competing with Jones for the closed end starting spot.

• Continuing with the defensive line theme here, Larry Webster had the hit of the practice, running right through Michael Williams to end the one-on-one drills. Webster said after that he just “worked one of my moves, converted speed to power.” It was enough to completely flatten Williams, who is transitioning from tight end to offensive tackle during this camp.

• The night practice was Jim Caldwell’s idea as part of trying to prepare his players for all situations, including potential night games like the one Detroit will play Friday at Oakland. He also did it because there is always the possibility the team could end up having a flexed game at some point during the season.

“It’s very, very important to get your team as many opportunities as you can to get ready for challenges that they may face and this is the time to do it, during training camp,” Caldwell said. “We don’t have the luxury during the regular season, we usually practice at a set time and typically not at night, so this is a time where you can adjust your schedule, move it around quite a bit. It’s not the normal routine, so it makes them adjust. I like the fact that they have to adjust.”

• More on this Wednesday morning, but Golden Tate participated in the ALS ice bucket challenge after practice. He also said the Lions offense received Shinola watches for beating the defense in a team bowling competition Monday night, but didn’t know who footed the bill for it.

• The Lions return to practice Wednesday at 2 p.m., the final practice open to the public this season.
