Houston Texans running back Arian Foster has claimed that he will have his best year in 2015, despite having no timetable on his return from injury.

The 28-year-old injured his groin during the pre-season which required surgery at the beginning of August, but Foster revealed that he has been hampered by knocks before and believes that he will return better than ever.

The four-time Pro Bowler told reporters: "I think this is going to be my best year and I still feel like it will be.

"It's going to be tough because I'm going to have some ground to make up, but I was feeling the best, feeling the quickest that I felt. You can judge for yourself."

Foster will miss the Texans' opening fixture against the Kansas City Chiefs on Sunday.
