It may be hard to believe, but Week 18 of the 2021 NFL regular season is upon us. The end of the NFL's longest-ever regular season promises to be a memorable one. Along with the top seed in the AFC, there are three playoff spots that seven teams will fight to earn this weekend. There are also several NFL records that could fall, including Michael Strahan's single-season sack record and Calvin Johnson's record for receiving yards in a season. 

As is the case every week, injuries will play a factor in what happens this weekend. The Titans made headlines on Wednesday when they designated running back Derrick Henry to return from injured reserve. Henry's return would surely big a big boost for a Titans team that is looking to secure the AFC's top seed with a win over the Houston Texans. 

As teams hit the practice field for the first time on Wednesday, we'll take a look at the initial injury reports to see which way some of those playmakers are trending heading into the rest of the week.

Chiefs (-10) at Broncos

Chiefs running back Clyde Edwards-Helaire missed his fifth consecutive practice. Edwards-Helaire did not play this past Sunday after sustaining a shoulder injury against the Steelers in Week 16. With Edwards-Helaire out, Darrel Williams rushed for 88 yards and two touchdowns on 14 carries during the Chiefs' 34-31 loss to the Bengals. Offensive lineman Orlando Brown -- who suffered a calf injury pregame last week -- was a full participant after being limited on Tuesday. Fellow lineman Lucaas Niang was held out. 

Denver placed Teddy Bridgewater on season-ending injured reserve on Wednesday. Bridgewater has not played since suffering a concussion during Denver's Week 15 loss to Cincinnati. The Broncos' offense will once again be led by Drew Lock, who threw for 398 yards with one touchdown in Denver's last two games. 

Cowboys (-5.5) at Eagles 

Cowboys fans were hit with the news on Wednesday that rookie phenom Micah Parsons was placed on the team's reserve/COVID-19 list. Parsons is vaccinated, a source tells CBS Sports, and has a chance to test out of the protocol this week. Meanwhile, safety Jayron Kearse (hamstring) and running back Tony Pollard (foot) were limited at practice. 

Philadelphia did not have offensive lineman Landon Dickerson (thumb), running back Miles Sanders (hand) and tackle Lane Johnson (knee). In the case of Johnson, however, the team notes he was given a rest day. Linebacker Shaun Bradley and quarterback Jalen Hurts were both limited. 

Packers (-11) at Lions

Green Bay held a walkthrough session on Wednesday, so their injury report is merely an estimation of what things would have looked like had they given it a full go. The Packers listed both quarterback Aaron Rodgers (toe) and defensive lineman (Kingsley Keke (illness) as non participants in the week's opening session. Meanwhile, tackle David Bakhtiari (knee), linebacker De'Vondre Campbell (elbow), tight end Dominique Dafney (ankle), and running back Aaron Jones (knee) were all limited.

Bears at Vikings (-3)

Titans (-10.5) at Texans 

Henry returned to practice Wednesday as the Titans began their 21-day window regarding his activation to the 53-man roster.

At practice, Julion Jones (hamstring) headlined the group of limited players, while defensive lineman Naquan Jones (knee) was the lone Titans player missing from the session.

The Steelers also placed defensive coordinator Keith Butler in the COVID-19 protocols. The Steelers activated several players from their COVID-19 list, including linebackers Devin Bush and Joe Schobert, defensive back Arthur Maulet and defensive end Chris WormleyBen Roethlisberger was limited in what was likely his final Wednesday regular season practice.

Guard Ben Powers (foot) was limited. 

Bengals at Browns (-3)

Having already clinched the AFC North title, the Bengals have ruled out quarterback Joe Burrow for Sunday's game.
