ALLEN PARK — Five Lions sat out the first day of the mandatory minicamp with an assortment of injuries. None appear to be serious.

Jason Fox, who had participated in all the organized team activities, was sidelined Tuesday.

“Anybody that didn’t practice today was injury related. Everybody is in town and here. we have a lot of things we’re trying to make sure they don’t roll up on us,’’ coach Jim Schwartz said. “Jason has had a good offseason, but his knee was getting a little sore so we decdied to shut him down.’’

Also missing were linebacker Stephen Tulloch, who has tendonitis in his knee; Louis Delmas (ankle): Sammie Hill and Chris Greenwood’s injuries are unknown. Cliff Avril was not present due to a contract dispute.

Tuesday’s session last just over an hour, but they’ll be on the field for about twice that time the Wednesday and Thursday, and then there will be rookie sessions after practice.

“Each step along the way, we’ve increased a little more. There have been different phases to our offseason program. This is a different phase.’’ Schwartz said. “... We’ve added just about everything in, we even walked through some goal-line stuff. We want to get everything that we’re going to install in training camp in by the time we’re doine here in minicamp so that everything in training camp is competition and physical, less trying to learn the system.’’
