Here’s what happened Friday at Halas Hall:

Santos still out

Kicker Cairo Santos, who made a surprise appearance on the Bears’ projected injury report Thursday, didn’t practice Friday, either. He has a problem with his right hip. Special-teams coordinator Richard Hightower didn’t elaborate, other than to say that he was “obviously dealing with something.”

The Bears have yet to add a kicker to their roster but would have to do so by 3 p.m. Monday if Santos isn’t in their plans. Jake Moody, who kicked in two games for an injured Santos last season, remains available.

Monangai, Stevenson practice

Running back Kyle Monangai (right knee) seems good to go for Monday. He was a full participant Friday. Cornerback Tyrique Stevenson (hamstring) practiced, albeit it on a limited basis, one day after the projected injury report said he would not have played.

Linebacker Noah Sewell (Achilles tendon) and defensive lineman Shemar Turner (knee) were both limited but can’t return until Week 5.

Rule change?

Hightower and fellow NFL’s special-teams coordinators met virtually late Friday to discuss a potential rule change. Last year, the NFL’s new kickoff rule allowed for a 12th player to hold the ball on the tee in case of weather. During the offseason, the league allowed it regardless of weather.

Last week, the Eagles had Braden Mann hold Jake Elliott’s ball at an angle — and not on a tee — to make for a nastier squib kick. The Falcons did it in Week 1. Hightower said that was against “the intent of the rule.” It wouldn’t be surprising if the rule was rewritten with a more clear directive.
