CINCINNATI -- With temperatures around southwest Ohio at their highest in a week and the humidity at similarly elevated levels, Cincinnati Bengals linebacker Vontaze Burfict had trouble completing Thursday afternoon's practice as a full participant.
According to the Bengals' injury report, the third-year player was "limited" in the practice with a non-injury, heat-related issue. The Bengals didn't provide specifics on what type of heat-related issue Burfict had, but they did say that he was not a full participant in the workout.
Burfict's partial absence came one day after he practiced fully in the wake of a hamstring injury that forced him out of the Bengals' Week 3 preseason game at Arizona. Wednesday was the first day the Bengals had to announce an injury report, and "full practice participation" was the designation they gave him. Burfict said earlier this week that he thought he'd be healthy enough from the hamstring injury to play Sunday when the Bengals visit Baltimore for the regular-season opener.
Along with Burfict, the Bengals also kept offensive linemen Clint Boling and Andrew Whitworth on the sideline Thursday, listed with non-injury related issues. In their case, it was a veteran's day off. Whitworth has been known to have those from time to time in his career, and Boling, who still is about nine months removed from ACL surgery, likely will be taking a few days here and there to keep his knee somewhat rested. The knee itself isn't an issue, but the team still wants to take it slowly with him and not put too much wear and tear on his legs early in the season.
The same goes for offensive guard Mike Pollak, who returned to practice Thursday after being completely sidelined Wednesday. He has a knee issue of his own that the Bengals have been cautious about.
In addition to those injury additions, the Bengals also still listed cornerback Darqueze Dennard (hip) as practicing in a limited capacity. He remains hopeful that he'll play Sunday after missing all but one play in the last three preseason games.
