Foster only featured in eight matches for the Texans last year having suffered a season-ending back injury that required surgery.
However, the 27-year-old has now been working out for two months and plans to participate in OTAs, which take place from May 27 to June 13.
"I'm fine. I got cleared, so I'm feeling good," Foster told the Houston Chronicle.
Foster managed just 542 rushing yards and one touchdown in his eight matches last season as the Texans slumped to a 2-14 record.
