Jackson has missed two games after suffering a broken rib against the Arizona Cardinals. He practiced on some level all week.
In his absence, the Texans have started Brice McCain at corner and moved Brandon Harris to the inside. With Jackson back, McCain should move back inside with Jackson back outside opposite cornerback Johnathan Joseph.
Jackson is targeted much less than Joseph; quarterbacks have targeted him 35 times this season.
The Texans lead the NFL in pass defense, giving up 171.8 yards per game. They've allowed 18 passing touchdowns, tied for the 15th most in the NFL with the Patriots and Cleveland Browns.
