ALAMEDA -- Defensive end Lamarr Houston, almost invisible against the Dallas Cowboys, plans to make amends.
The Raiders' best and most consistent lineman had just two tackles and had no impact as a pass rusher against Cowboys left tackle Tyron Smith in a 31-24 loss and is determined to make up for it against the New York Jets on Sunday at MetLife Stadium.
"I've got to definitely show improvement this game and bring it, because that was probably the worst game I think I've played in my life," Houston said Thursday.
In his fourth season out of Texas, Houston leads Raiders defensive linemen with five sacks and is consistently the most disruptive in terms of pressures. Along with left tackle Jared Veldheer, Houston will be among the most sought-after Raiders in unrestricted free agency if not re-signed by the club.
Houston has watched the Dallas film closely and was unsparing in his self-critique.
"In certain situations I probably should have used different rushes," Houston said. "I don't think I was picking my moves well. My timing was off. The aiming point I was using to come at the tackle was bad. I should have studied more and thought about the depth of their linemen."
There is more detail work planned in getting ready for the Jets and left tackle D'Brickashaw Ferguson.
"I think with the short week, I didn't do a good job of preparing myself," Houston said. "It's a skill that comes with a lot of preparation and a lot of details."
"He's better. He's still not fully ready to go," coach Dennis Allen said. "We still have a couple of days to see where we're at."
With Darren McFadden (ankle) and Jeremy Stewart (knee, ankle) still not practicing, Marcel Reece probably would be the lead running back if Jennings can't play. He would be spelled by Taiwan Jones, switched back to running back from cornerback on Wednesday.
Jennings will do as ordered by doctors.
"I never in my life have been in a locker room and not planned to play," Jennings said. "And never in my life have I made the decision whether I'm playing or not."
"He was able to do more today," Allen said of Branch. "That was a good sign. We're going to continue to work him and try to get him back into football shape and see when he'll be ready to go."
Branch has missed the past 10 games with an ankle injury.
