Midfielder Westwood suffered a serious right leg injury following a collision with West Ham's Nikola Vlasic in the 22nd minute and left the field on a stretcher. The match ended 1-1.
"He is going to see a surgeon today and the doctor has gone with him," Jackson told reporters. "I don't know if it is a break or a dislocation, we will know after that if he needs an operation."
Burnley, 18th in the league and three points from safety, host 12th-placed Southampton on Thursday.
