NASHVILLE, Tenn. -- Tennessee Titans coach Mike Vrabel on Friday ruled out wide receiver A.J. Brown for Sunday's game against the Jacksonville Jaguars. Brown didn't practice all week because of a bone bruise on his knee.

The second-year receiver wasn't listed on last week's injury report. Brown missed consecutive days during training camp and wore a band on his left knee when he returned.

Brown is expected to be a big part of the Titans' passing game this season. He posted 52 receptions for 1,051 yards and eight touchdowns as a rookie last year.

Brown was targeted eight times in the season opener against the Denver Broncos and finished with five receptions for 39 yards. Corey Davis led the Titans with seven receptions for 101 yards.

Davis was limited in practice this week. If Davis is unable to play, the Titans will be without their top two receivers. Davis was listed as questionable before last week's game because of a hamstring injury.

Vrabel said rookie running back Darrynton Evans (hamstring) has also been ruled out for Sunday.
