Tennessee Titans running back Chris Johnson, center, gets past Indianapolis Colts middle linebacker Pat Angerer during the second quarter of an NFL football game in Indianapolis, Sunday, Dec. 18, 2011.

NASHVILLE, Tenn. — Chris Johnson says he originally feared he had hurt his right ankle badly, but says he expects to be able to play Saturday as Tennessee (7-7) tries to keep its faint playoff hopes alive against the Jacksonville Jaguars.

At first, Johnson thought the injury was worse than the one he sustained in a playoff loss to Baltimore.

This has been Johnson's worst season after missing all preseason before signing a $53.5 million extension. Yet he is 70 yards away from 1,000 yards rushing for the season, which looked unlikely considering his struggles over the first half of the season.

Jacksonville's Maurice Jones-Drew is the NFL's rushing leader.
