The centre-back faced a late fitness test ahead of Sunday's FA Cup win over Portsmouth, and despite picking up a knock during the game, expects to feature against the Black Cats
Having already had a problem with his left knee of late, the Blues defender hit his right one against a post while clearing the ball off the line in his side’s 4-0 FA Cup win against Portsmouth last weekend.
The centre-back reportedly required a late fitness test to face the Championship side at Stamford Bridge, but remains confident he will be able to feature for the visit of Martin O'Neill's men.
“I have been struggling with the other knee but I clattered into the post with my right knee,” Terry told the club’s official website.
“All is fine. It's a little bit swollen but I am sure with the couple of days off we have, it will heal.”
The England skipper has played in all 20 of the Blues’ Premier League games so far this season.
