Washington Redskins wide receiver Cam Sims had a great underdog story going last year -- until the opening kickoff of the 2018 NFL season.

After catching 41 passes during his four-season Alabama career, Sims led the Redskins with five catches for 131 yards in the preseason and made the regular-season roster as an undrafted rookie.

But blocking on the kickoff-return team in the opening seconds of the 2018 season, Sims suffered a high ankle sprain against the Arizona Cardinals. Carted off the field, he didn't play again the entire season.

“Every Sunday, I would cry because I wasn’t out there playing,” Sims told Kyle Stackpole of the Redskins’ official website. “I just had to get up out of that. After I stopped crying, I was just like, ‘Man, let’s go. I can’t do that. Let’s go. Let’s go do something. Let’s go work.’”

Sims has been working toward his 2019 plan as a steady presence at the Redskins’ facility this offseason after his “redshirt” season.

“To pick up where I left off,” Sims said of his objective. “Just to keep going and going. I know I had a great year last year before I got hurt, so I just want to pick up and do better than I did last year.”

Washington placed Sims on injured reserve after he got hurt. He recovered before the season ended, but he couldn't return to the field. Each NFL team is allowed to activate two players a season from IR, and the Redskins brought back wide receiver Trey Quinn and running back Byron Marshall in 2018.

Sims rejoins a thin wide-receiver corps with the Redskins.

Washington's top wide receiver in 2018, Josh Doctson, caught 44 passes for 532 yards and two touchdowns. The next two wide receivers on the Redskins' stat list in 2018 are no longer on the team, with Jamison Crowder going to the Pittsburgh Steelers and Maurice Harris leaving for the New England Patriots in free agency.

Paul Richardson will be back after playing in only seven games in 2018. He caught 20 passes for Washington. The other seven wide receivers on the Redskins' current roster combined for 14 receptions in 2018.
