With week two of the NFL season having wrapped up, apart from tonight's Monday night game, teams are already trying to manage and overcome injuries. However, not all injuries are created equal in terms of who gets injured and these notable players will be difficult to replace.

Kevin Johnson to miss time with MCL sprain

Kevin Johnson, one of the Houston Texans' starting cornerbacks, was injured in the team's 13-9 victory over the Cincinnati Bengals on Thursday night. ESPN's Adam Schefter reported that the team's 2015 first-round pick will miss four to six weeks due to a sprained MCL.

This is the latest setback for the 25-year-old Johnson, who only played six games last season after he broke his foot and had to be placed on injured reserve. It is likely that Marcus Burley, who the team signed almost three weeks ago, will play a major role in filling in for Johnson.

Jamie Collins suffers concussion

Cleveland Browns linebacker Jamie Collins left yesterday's 24-10 loss to the Baltimore Ravens in the fourth quarter with a concussion, according to ESPN's Pat McManamon. He will now enter concussion protocol and be out for an unknown amount of time since concussions vary in severity.

This offseason the Browns gave the 27-year-old a four-year, $50 million contract extension and clearly view him as a building block on their defense, so his loss will hurt. Collins will either be replaced by first-year linebacker James Burgess or 2015 second-round pick Nate Orchard.

Falcons lose Vic Beasley

Atlanta Falcons linebacker Vic Beasley left last night's game in the third quarter with a hamstring injury as the Falcons put on an impressive victory, defeating the Packers 34-23.

Following the game, Zach Klein, the sports director for WSB-TV Atlanta, reported that Beasley was expected to miss about a month due to the injury.

Losing him is a big blow to the Falcons' defense, as Beasley had a league-leading 15.5 sacks last season. For comparison, the rest of the Falcons' defense only had 18.5 sacks in 2016.

Now, the team's first-round pick Takkarist McKinley will have to step up right away for the Falcons' defense in the pass rushing department.

Mike Daniels also suffers hamstring injury

On the other side of the ball, the Green Bay Packers also lost defensive end Mike Daniels to a hamstring injury last night. Losing him will be a big blow to the Packers' defense, as Daniels is considered their best defensive lineman and has been the team's full-time starter since taking over the job in 2014. The team is currently awaiting test results but the injury is not believed to be serious according to ESPN's Rob Demovsky:
