Dallas Cowboys star Dak Prescott wants to suit up to play the Minnesota Vikings in the NFL this week but conceded whether he does is not "fully my decision".

Prescott is battling to overcome a calf strain in time for the Cowboys' clash with the Vikings in Minnesota on Sunday.

The Cowboys quarterback and two-time Pro Bowler has been limited to two days of practice.

"Knowing this is a long journey and a long season, I don't necessarily know if this is fully my decision, but I'm just going to keep controlling the things I can to get better," Prescott told reporters on Thursday.

"I've gotten better each and every day, and that's what is most important. I'm just focused on doing that again tomorrow."

On the thresholds he will have to pass in practice in order to play according to head coach Mike McCarthy, Prescott added: "They didn't tell me which ones I've got to pass.

"Obviously I trust myself, trust my body, trust what I'm thinking, but also I trust the coaches and Britt, Jim [Maurer] and the whole training staff. We've put a lot into this. I've put a lot into my body and taking care of myself.

"But they know. They know how these things work. First time dealing with something like this, obviously on the same leg as my ankle, I want to be smart about it and cautious. But as I've said, I've gotten better each and every day. I'm doing things today I didn't do as well the day before. I think that's huge."

Prescott has thrown at least three touchdown passes in each of his last four games. According to Stats Perform, it is the longest such streak in Cowboys history – Patrick Mahomes is the only other NFL player with a streak of four consecutive games throwing at least three TD passes this season.

Dallas QB Prescott boasts a 73.1 completion percentage, which is only second to Arizona Cardinals star Kyler Murray (73.5), while his passer rating (115.0) is fourth in the league.

Overall, Prescott has completed 158 passes for 1,813 yards, 16 touchdowns and four interceptions for the 5-1 Cowboys in 2021.
