The continued absence of fullbacks Marcel Reece and Richard Gordon has the Raiders contemplating options for Sunday's game against the Texans in Houston.
Both players missed practice Thursday, making it possible, if not likely, that neither will be available on game day. Reece has an ankle injury and Gordon, a tight end who subbed at fullback against New England, a broken hand.
Coach Hue Jackson floated the idea of using Rock Cartwright, 5-foot-8 and 215 pounds, if necessary. Cartwright was drafted as a fullback at Jackson's request by the Washington Redskins in 2002 but was 20 pounds heavier then.
"I've never been used in practice as a fullback, but I always take it upon myself to prepare as if I'm going to be the starter,'' Cartwright said.
If the Raiders use Cartwright in some sets as a fullback, tight end Brandon Myers could fill in as a blocker in sets where more size is needed.
Another option would be promoting San Mateo product Manase Tonga from the practice squad. Tonga, 5-11, 245 pounds, is the only healthy true fullback on the practice field and has been working with the first-team offense.
"I haven't heard anything yet, but I'll be ready just in case,'' Tonga said. "I took the majority of the reps today, and feel pretty good about it.''
Tonga, from Aragon High, went to college at BYU, signed with the Raiders as an undrafted free agent and spent the 2010 season on the practice squad.
Pryce, 36, played in 10 regular-season games for the New York Jets last season and played well in a 28-21 playoff win over New England. Pryce has played with Denver (1997-2005) and Baltimore (2006-2010). He played three games with the Ravens last season before being released and signing with the Jets.
Discussions with Pryce could indicate concern over the shoulder of defensive end Matt Shaughnessy, who has missed the past two games and hasn't practiced this week.
"I knew if he was really given a shot, he'd make the most of it,'' Foster said. "He was one of my really good friends at Tennessee, and it's really good to see him doing good things."
Those who did not participate besides Reece, Gordon and Shaughnessy included cornerbacks Chimdi Chekwa (hamstring) and Chris Johnson (groin).
Johnson, who had sports hernia surgery late in training camp, was listed last week as out with a hamstring injury. This week the NFL report lists him with a groin injury.
Chekwa aggravated his injury Wednesday. If he can't play, the likely starter would be third-round pick DeMarcus Van Dyke.
