ALLEN PARK — Between the heat and what Lions coach Jim Schwartz calls “camp knee” more players did not make it through Friday’s practice.

Wide receiver Ryan Broyles, who is coming off ACL surgery, was having trouble keeping the tape on his knee due to the humidity and sat out part of practice.

Titus Young and Corey Williams also had that minor knee issue and didn’t finish.

“We’ve got a lot of camp knees. No real injuries, just guys that get sore form a lot of reps,’’ Schwartz said. “... The whole idea, there’s a lot of things we want to push through, we want to push through when you’re hot, when you’re out of wind you need to be able to go. We don’t want to push through knee soreness or hamstrings,’’ the coach added.

A few players, including Ronnell Lewis, had trouble with the heat and went in for intravenous fluids.

Schwartz had no complaints about the heat and humidity.

“It’s good from a standpoint of we’re not a hot weather city so when we get nice hot humid weather like this it’s great to practice in and great for our conditioning,’’ Schwartz said.

Still out with injuries were Stephen Tulloch (tendonitis), Louis Delmas (knee), Jahvid Best (concussion) and Mikel Leshoure (hamstring).
