Justin Forsett’s mantra is Carpe Diem — seize the day.

“In this league, opportunities are few and far between. You’ve got to take advantage when they’re there. It’s a blessing just to have an opportunity to go out and compete every day,’’ the veteran running back said.

Signed as an unrestricted free agent to a two-year $2 million deal to give the Jaguars more depth at running back, Forsett is getting an opportunity because Maurice Jones-Drew is still recovering from surgery last December for his Lisfranc foot injury.

Since Jones-Drew hasn’t been able to practice yet and is rehabbing in Miami, Forsett has been getting a lot of work in the organized team activities (OTAs).

Forsett is part of the running back rotation along with rookie Denard Robinson and Jonathan Grimes, who was signed last December. Jordan Todman also may be in the mix once he recovers from a knee injury.

Forsett said, “You go out every day and get more reps. You get acclimated with the quarterbacks. More reps never hurt.’’

Forsett doesn’t know what the future holds for him. But even if Jones-Drew comes all the way back, Forsett is trying to show there’s a place for him.

“Definitely, this is the way this league works. I’ve been in different positions. I’ve been a starter and I’ve been a backup. I know that any given moment, you have to be ready when an opportunity presents itself,’’ he said.

Forsett was signed by the Jaguars as a sort of insurance policy. When Jones-Drew went down in the sixth game last year, he had 414 yards and wound up leading the team in rushing.

Rashad Jennings was supposed to fill the void, but he got hurt and wound up with 283 yards.

The Jaguars hope Forsett will be more productive if he’s called on.

When coach Gus Bradley was asked if Forsett is the guy with Jones-Drew rehabbing, he said, “He is. You can count on him, steady, always does things right, had a good last year [in Houston]. I know in talking with some of their staff earlier they felt strongly about him just the same way I felt about him when we were in Seattle. So I think he brings that continuity to what we have. He raises the level of play throughout the whole running backs.’’
