Swift (groin) will get some reps in team drills Thursday, but he's ruled out for Saturday's preseason game against Pittsburgh, Dave Birkett of the Detroit Free Press reports.
Swift previously was expected to resume practicing Tuesday, which might've given him a chance to be cleared for the game this weekend. In any case, he could make an appearance in the final week of the preseason, or the Lions could wait until Week 1 to unleash their lead back. It's still unclear how much work Swift will lose to offseason addition Jamaal Williams, who took all the first-team reps in the exhibition opener. Swift has been dealing with a groin injury since the first week of August.
