BOURBONAIS, Ill. -- A daily review of the hot topics coming out of Chicago Bears training camp:

• Several players injured earlier in camp returned to action on Sunday, while safeties Chris Conte and Craig Steltz came off the physically unable to perform list. Cornerback Tim Jennings (quadriceps) practiced along with Kyle Long (ankle), after both missed the preseason opener Friday against the Philadelphia Eagles. Defensive end Jared Allen also returned to practice after missing multiple days to be with family for the birth of his daughter. Conte took some repetitions with the starters, but spent the majority of the day working with the backups.

• Obviously the time spent watching Charles Tillman is helping Sherrick McManis, who executed a perfect punch to knock the ball out of the arms of Micheal Spurlock after he made a catch on an intermediate pass.

• Non-participants at the workout Sunday included right tackle Jordan Mills, who was wearing a walking boot on his right foot, along with Eben Britton (hamstring), Chris Williams (hamstring), Isaiah Frey (hamstring), and Brian De La Puente (knee).

• Having returned from an indefinite suspension earlier in the day, tight end Martellus Bennett drew loud applause from the crowd after he caught a pass near the sideline. Bennett stayed after practice to run extra springs with Conte, Steltz, Jennings, Alshon Jeffery, Josh Bellamy, Matt Forte, Armanti Edwards and Josh Morgan. Bennett and rookie quarterback David Fales continued to run after everyone else had left the field.

• Ryan Mundy and Danny McCray continue to work with the starters at safety. Both starting positions remain up for grabs.

• The practice on Sunday attracted the largest crowd so far at camp. There were 18,500 in attendance at the workout on the campus of Olivet Nazarene University.

• The Bears practiced in shorts, helmet and shoulder pads, and the workout was one of the most lively sessions of camp, which is somewhat impressive considering the team had just played in a preseason game two days prior.
