However, the Titans revealed that the injury was not as serious as first believed.
The team said in a statement: "We received reassuring reports from the second MRI today and they confirmed that there was no major damage to Jake Locker's hip joint - it is classified as a sprained hip.
"The area will need time to heal and strengthen, but he won't require surgery and he has already begun a rehab routine for both his hip and knee.
"We certainly would expect him to miss a few weeks, but we are encouraged by the news today."
The Titans are 3-1 in their season after week four.
