When New England players began taking the field for pregame warmups a short time ago, Harris was out there doing his normal work, per ESPN's Mike Reiss.
The former Alabama star is coming off a massive 103-yard, three touchdown performance in last week's loss to the Buffalo Bills. He missed the Patriots' Week 15 contest the week before with his hamstring issue.
Harris has rushed for 12 touchdowns in 13 games this season, reaching the end zone in eight of his last nine appearances.
As long as he's healthy enough to play, he's not a bad bet to score once again this afternoon against a woeful Jacksonville Jaguars team.
Kickoff for Pats-Jags is set for 1 p.m. ET at Gillette Stadium.
