RICHMOND – When Chase Minnifield steps on the field Thursday night as the Redskins open the preseason against the Tennessee Titans, it will mark the end of a 20-month wait for the first-year cornerback.

After suffering a season ending knee injury in 2011 that required microfracture surgery, the University of Virginia product made it back to the field the following summer as an undrafted rookie signed by the Redskins. But on the final day of offseason practices, Minnifield tore his anterior cruciate ligament and missed all of the 2012 season.

Now, just more than a year later, Minnifield finally will play his first game since his college career ended. After working his way back into the groove during offseason practices and impressing coaches and teammates during the opening stretch of training camp, Minnifield welcomes the next opportunity to prove himself.

“I can’t wait to play in a game,” Minnifield said. “It’s been a long time. I just want to go out there and play hard – keep doing what I’ve been doing in practice here and take it into games.”

Minnifield finds himself in a battle for a roster spot at a position that boasts three seasoned veterans in DeAngelo Hall (10th season), Josh Wilson (eighth) and E.J. Biggers (fifth), and a cast of young competitors like second-year pro Richard Crawford, rookie David Amerson and journeymen Ryan Mouton and Jerome Murphy.

Hall, Wilson, Biggers, Amerson and Crawford all seem to have spots locked up on the 53-man roster, and a strong performance Thursday should go a long way toward ensuring Minnifield remains on track to earn a job as well.

With Hall not expected to dress for the game while nursing ankle and finger injuries, Amerson likely will start at left corner. But Minnifield should see a fair amount of action, and possibly early in the game. Tuesday in practice, Minnifield took over for Hall after the first round of 11-on-11 drills, lining up opposite Amerson, who took Wilson’s place at right corner.

Minnifield struggled to describe what kind of pregame emotions he expected to experience, but he aims to channel whatever feelings he has into a solid performance against the Titans.

“I’m not really sure what to expect,” Minnifield said Tuesday. “I just know I’ll go out there, play hard and count my blessings, because I know it’s a blessing to be able to go out and play.”
