Kansas City signed Holiday to the practice squad Wednesday.

Holiday spent time with the Chiefs this offseason then bounced on and off the team's practice squad early in the regular season. He then landed on Seattle's practice squad late November, and the Seahawks cut him Dec. 13. Now, Holiday will resume handling an emergency depth role with Kansas City.

London (knee) practiced in a limited fashion Wednesday, Tori McElhaney of the Falcons' official site reports.

London has missed the past four games due to a PCL sprain in his left knee, but his return to practice Wednesday was preceded by coach Raheem Morris telling Marc Raimondi of ESPN.com that the wide receiver now is considered "day-to-day." London will have two more chances to mix into drills this week to prove his health ahead of Sunday's contest at Arizona.

Wicks (ankle) practiced in a limited capacity Wednesday.

Wicks was sidelined for Tuesday's walkthrough, so his ability to mix into drills one day later is a step in the right direction ahead of Saturday's game in Chicago. Ultimately, Thursday's practice report will reveal whether or not he's tagged with a designation for Week 16 action.

johnston (groin) is participating in practice Wednesday, Kris Rhim of ESPN.com reports.

Johnston was added to Los Angeles' injury report in Week 15 late after being limited at practice Friday, and he was initially listed as questionable before eventually being ruled out for the team's win over the Chiefs. It seems likely that he'll be limited again Wednesday, in which case the extent of Johnston's practice activity Thursday and Friday stand to be the deciding factors in his status for Sunday's game against Dallas. Even if healthy enough to return in time for a favorable matchup against the Cowboys' defense, it will be difficult for fantasy managers to rely on Johnston given that he's exceeded 50 receiving yards just once in his last eight appearances.

Watson (chest/shoulder) said Wednesday that he's "feeling pretty good" and expects to be "alright for the game" against Chicago on Saturday, Matt Schneidman of The Athletic reports.

Watson was down on the ground for a while after an awkward fall during Saturday's 34-26 loss to the Broncos. He didn't rejoin the game, and was even sent to the hospital briefly, but he flew home with his teammates Sunday night before managing limited practice participation Wednesday.

Burden (ankle) was a non-participant at practice Wednesday.

Burden filled in for an absent Rome Odunze (foot) this past Sunday versus the Browns, hauling in six of seven targets for 84 yards before exiting in the third quarter with an ankle injury. On Monday, coach Ben Johnson called Burden "day-to-day," per Chris Kwiecinski of Fox 32 Chicago, but both he and Odunze have yet to mix into any drills this week. Thursday's practice report will reveal Burden's odds to suit up Saturday against the Packers.

Odunze (foot) didn't participate in Wednesday's practice.

Odunze sat out a Week 14 loss at Green Bay due to a stress fracture in his foot, and while he was listed as active this past Sunday against the Browns, he was a late scratch due to a setback suffered during pregame warmups. On Monday, coach Ben Johnson told Courtney Cronin of ESPN.com that "all options are on the table" for Odunze's recovery, but the second-year pro now has missed both Week 16 sessions, putting his availability in question ahead of Saturday's game versus the Packers.

Davis (ankle) didn't practice Wednesday, Kris Rhim of ESPN.com reports.

The third-year pro was sidelined for the Week 15 win over the Chiefs due to an ankle injury, and Wednesday's DNP suggests he's still dealing with the issue. Davis likely needs to upgrade to at least limited practice Thursday or Friday to play in the Week 16 matchup against the Cowboys on Sunday.

Horn recorded a seven-yard reception on his lone target in Sunday's 20-17 loss to the Saints.

Horn took the field for just four of Carolina's 57 plays on offense, marking the fourth straight game he played single-digit snaps. He had played double-digit snaps in all but one of Carolina's six games between Weeks 5 and 10, but Brycen Tremayne appears to have since leapfrogged him on the depth chart as the Panthers' preferred No. 4 wideout behind Tetairoa McMillan (foot/ankle), Xavier Legette and Jalen Coker.

Mims hauled in four of his six targets for 29 yards and carried once for eight yards in Sunday's 34-26 win over the Packers. He also returned a kickoff for 37 yards.

Mims checked out at one point of Sunday's game to be evaluated for a concussion and was ultimately diagnosed with a stinger, but he was cleared to return to action and ended up playing 21 of the Broncos' 68 offensive snaps. His 31 percent snap share was roughly on par with his rate from the last few weeks, as he continues to handle more of a part-time role on offense. The Broncos were notably without rookie wideout Pat Bryant (hamstring) on Sunday, so if Bryant returns for a Week 16 matchup with the Jaguars, Mims would probably be more likely to see his snap share decline than hold steady or increase.
