Cowboys waive DT Stewart Praised by Parcells in training camp, veteran is waived 09:03 PM CDT on Tuesday, September 14, 2004 By TODD ARCHER / The Dallas Morning News IRVING – Defensive tackle Daleroy Stewart, whom coach Bill Parcells said in training camp could be a dominant player, was waived Tuesday to make room for fellow defensive tackle Leonardo Carson. Carson was suspended for last Sunday's game by the NFL for violating the league's personal conduct policy but was back at the Valley Ranch facility Monday. Because of league rules, Carson was not allowed to be with the team last week and spent his time at a local gym. He watched Sunday's loss at Minnesota on television. "I worked out for two hours a day trying to stay in some sort of football shape," Carson said. "I didn't want to get out of sync." The recent acquisition of Chris Cooper from Oakland left Stewart vulnerable to a possible move. After seeing no action in his first two years with the Cowboys, Stewart played in 15 games in 2003 and had 17 tackles and 1 ½ sacks, but he failed to improve upon a solid off-season during training camp. The Cowboys have four defensive tackles on the roster with Carson, La'Roi Glover, Chad Eaton (who replaced Carson in the starting lineup Sunday) and Cooper. New DT ready to play: Newly acquired defensive tackle Chris Cooper said he will be available to play Sunday against Cleveland, but he will need some time to adjust to his new team. "It's real exciting to come to a defense that was No. 1 last year compared to coming from the last-ranked defense," said Cooper, who was acquired from Oakland on Saturday. Cooper, who was bothered in training camp by a calf injury, said he was aware a trade was possible when his repetitions were cut down in practice. Last year, Cooper had 49 tackles and 2 ½ sacks. The NFL fined him three game checks for testing positive for the designer steroid THG. Rookie may be needed: Because of the uncertain status of right guard Andre Gurode and center Tyson Walter, who suffered knee injuries against Minnesota, the Cowboys might have to activate rookie guard Ben Noll on Sunday vs. Cleveland. The Cowboys claimed Noll off waivers from St. Louis after the final cuts. He practiced with the team only last week, but coach Bill Parcells liked what he saw in Noll during the Rams' preseason. "He's pretty smart, so I think he'll know the system," Parcells said. "We're going to have to work him some this week for sure." Briefly: The Cowboys added offensive lineman Thomas Herrion to the practice squad and let go cornerback Lenny Williams. Herrion, who was one of the Cowboys' last cuts, was needed to supply depth with injuries to Andre Gurode and Tyson Walter.
