Crockett has played fullback for the Raiders since joining the team in 1999 but was moved to tailback during training camp to provide relief for LaMont Jordan. He had 20 yards on three carries against the Patriots in spot appearances in the second half.
While praising John Paul Foschi, the converted tight end who started at fullback against New England, Turner said it came down to the Raiders needing to get Crockett on the field more.
''He's a very good pass protector (and) he's a good player,'' Turner said. ''He is still going to get the ball at tailback when he is in the game at tailback. When you look at the game last week, and he had 10 plays, he is a guy who should be on the field 25 times a game.''
Putting Jordan and Crockett in the same backfield could be an indication the Raiders are looking to run the ball and control the clock against the Chiefs more effectively than they did in the loss to New England.
Oakland called only 21 designed running plays against New England. Jordan, who finished with 70 yards on 18 carries, only ran the ball four times in the second half when the Raiders essentially abandoned the ground game entirely.
In other news:
* Turner said that wide receiver Doug Gabriel might play against the Chiefs, a slight change from his statements earlier in the week. Gabriel practiced on Friday and is eager to get back on the field, but Turner said a decision won't be made until Sunday.
* The Chiefs downgraded left tackle Willie Roaf to doubtful, meaning Kansas City will be without one of its top offensive linemen. Losing a player of Roaf's talents would be a blow to any team but the Chiefs feel they have enough depth up front that they won't alter their offensive approach.
